DESCRIPTION:Dr. Sandro Tacchella\NFirst Insights from JWST: Star Formation in Cosmic-Dawn Galaxies\NMonday 3rd July 2023 @ 11h15\NAfter successful deployment and commissioning, JWST has now been delivering data for over a year. In this plenary talk, I will give an overview of the first-year surprises and discoveries, zooming in on some of the earliest galaxies and presenting new results on the spatially resolved growth histories of high-redshift galaxies. Specifically, I will discuss the structural and stellar population properties of the galaxies at the redshift frontier, with redshifts z>10. I will then connect the mode of star formation with the early enrichment of galaxies: for galaxies where we have constraints on the gas-phase metallicity (at redshift of z=8), I will discuss how star-bursting galaxies can have different gas-phase metallicities due to internal and external mechanisms that drive the starburst. Finally, I will focus on the structural evolution of galaxies, presenting how bulges form within galaxies at z>7. I will wrap up by highlighting what JWST will be able to deliver regarding high-redshift galaxy evolution in the upcoming years.

DESCRIPTION:Prof. Erminia Calabrese\NPrecision cosmology with the Cosmic Microwave Background\NMonday 3rd July 2023 @ 12h00\NThe use of the Cosmic Microwave Background (CMB) to study the physics of the Universe is one of the greatest success stories of modern cosmology. This light, travelling since ~380,000 years after the Big Bang, contains relic signatures of the physical processes that took place much earlier, at incredibly high energies, as well as unique features allowing us to determine precisely the abundances of the main constituents of our Universe, which govern its evolution on large scales. In particular, during the last three decades, the astonishing agreement between the theory and increasingly-precise observations of the CMB has led to the establishment of our standard model of cosmology. While the parameters of this model have been constrained to sub-percent precision, many fundamental questions about the Universe are still unanswered. In this talk I will give a snapshot of where we are in CMB cosmology, how we got here and where we are heading next, as new, more powerful CMB data are being collected, analysed and planned for.

Key "Origins"
This key Origin session addresses the recent observational and theoretical developments regarding the early evolution of galaxies, focusing on the first 2 billion years of cosmic history. The main aim is to bring together experts to present and discuss recent insights on the following topics: - Detection and characterisation of the first stars and galaxies - Early metal enrichment and dust evolution in galaxies - Impact of reionization on star formation and the impact of galaxies on the reionization of the intergalactic medium - Morphological evolution: emergence of the first disk galaxies, size evolution and bulge formation - First quiescent galaxies and their implications for quenching processes - Growth of supermassive black holes and the feedback from AGN on early galaxy formation.

Key "Origins"
This key Origin session addresses the recent observational and theoretical developments regarding the early evolution of galaxies, focusing on the first 2 billion years of cosmic history. The main aim is to bring together experts to present and discuss recent insights on the following topics: - Detection and characterisation of the first stars and galaxies - Early metal enrichment and dust evolution in galaxies - Impact of reionization on star formation and the impact of galaxies on the reionization of the intergalactic medium - Morphological evolution: emergence of the first disk galaxies, size evolution and bulge formation - First quiescent galaxies and their implications for quenching processes - Growth of supermassive black holes and the feedback from AGN on early galaxy formation.
These topics are all closely interconnected. The first galaxies - their abundance and properties - are a sensitive probe of stellar feedback and different dark matter models. The stellar populations of those galaxies are largely unknown (Pop III vs Pop II), though we know that those stars fused heavy elements, which enriched the interstellar and circum-galactic medium, and led to the production of dust. Black holes from unknown seeds grew in those galaxies, leading to some of the brightest and most energetic objects in the universe. The stars, and possibly also accreting black holes, in high-redshift galaxies transformed reservoirs of cold, neutral gas across the cosmos into a hot, ionized state, though the protagonists of cosmic reionization remain elusive. Therefore, the study of the evolution of galaxies from the Dark Ages to Cosmic Noon, including the morphological evolution (establishment of the Hubble Sequence) and the formation of the first quiescent galaxies, is of great importance for shedding new light onto star formation and feedback from stars and black holes.

Finally, the detailed study of the CMB frequency spectrum - a unique probe not yet unlocked by existing experiments - would allow us to shed light on interactions deep into the pre-recombination era. This could deliver a new test of inflation at scales far smaller than currently observed, and a direct way to study the dynamics of the recombination process, potentially uncovering new physical effects that relate to the tensions in cosmology. In the near future, a series of ground-based and satellite-borne CMB experiments promise to deliver new breakthroughs in cosmology and fundamental physics.

The UK CMB community is strongly involved in the development of these experiments (with UKRI and UKSA support for participation into Simons Observatory and LiteBIRD), leading key contributions in instrumentation and data analysis.

The innermost regions of the disc, within a few au from the protostar, play a crucial role in the physics of the entire disc, as well as in the formation of planets. Within this region, large amounts of energy are released into the system, influencing the energy balance of the full disc; dust particles evaporate at the dust sublimation point, and terrestrial planets may form. Accretion and ejection processes have an impact on the protostellar evolution. Facilities like VLT (e.g., XSHOOTER, SPHERE) and VLTI (e.g., GRAVITY and MATISSE) have made a lot of progress in detecting the inner gaseous and dusty disc and measuring the accretion and ejection properties of young stars. At mm wavelengths, ALMA completely changed our view on protoplanetary discs where unexpectedly, discs were found to consist of a series of bright symmetric nested rings and a plethora of different disc structures and shapes were present in the discs of young stars. Since then, much work has been done in studying the dust and gas component of the disc as well as looking for planets. Although these ring and spiral structures are present in discs it is still not clear whether all these structures are created from planets or not. Proper modelling is needed in order to understand these structures as well as connect the inner and outer disc observations.\N \NTopic:\NPlanets/Stellar

Within this region, large amounts of energy are released into the system, influencing the energy balance of the full disc; dust particles evaporate at the dust sublimation point, and terrestrial planets may form. Accretion and ejection processes have an impact on the protostellar evolution. Facilities like VLT (e.g., XSHOOTER, SPHERE) and VLTI (e.g., GRAVITY and MATISSE) have made a lot of progress in detecting the inner gaseous and dusty disc and measuring the accretion and ejection properties of young stars. At mm wavelengths, ALMA completely changed our view on protoplanetary discs where unexpectedly, discs were found to consist of a series of bright symmetric nested rings and a plethora of different disc structures and shapes were present in the discs of young stars. Since then, much work has been done in studying the dust and gas component of the disc as well as looking for planets. Although these ring and spiral structures are present in discs it is still not clear whether all these structures are created from planets or not. Proper modelling is needed in order to understand these structures as well as connect the inner and outer disc observations.

Key "Origins"
This key Origin session addresses the recent observational and theoretical developments regarding the early evolution of galaxies, focusing on the first 2 billion years of cosmic history. The main aim is to bring together experts to present and discuss recent insights on the following topics: - Detection and characterisation of the first stars and galaxies - Early metal enrichment and dust evolution in galaxies - Impact of reionization on star formation and the impact of galaxies on the reionization of the intergalactic medium - Morphological evolution: emergence of the first disk galaxies, size evolution and bulge formation - First quiescent galaxies and their implications for quenching processes - Growth of supermassive black holes and the feedback from AGN on early galaxy formation.
These topics are all closely interconnected. The first galaxies - their abundance and properties - are a sensitive probe of stellar feedback and different dark matter models. The stellar populations of those galaxies are largely unknown (Pop III vs Pop II), though we know that those stars fused heavy elements, which enriched the interstellar and circum-galactic medium, and led to the production of dust.

To help unravel these mysteries, ESA's Solar Orbiter spacecraft was launched in 2020 as the most complex scientific laboratory we have ever sent towards the Sun. After two years of cruise phase, Solar Orbiter is now taking coordinated images of the Sun from closer than any spacecraft before along with measurements of the plasma environment that makes up the heliosphere. Using these combined observations, together with existing space and ground based solar and heliospheric measurements, scientists hope to find answers to some profound questions: What drives the Sun's 11-year cycle of rising and subsiding magnetic activity? What heats up the upper layer of its atmosphere, the corona, to millions of degrees Celsius? What drives the generation of the solar wind? What processes occur and modulate the solar wind as it expands through the heliosphere? What accelerates the solar wind to speeds of hundreds of kilometres per second? And how does it all affect our planet? This session aims to discuss these relevant scientific questions by inviting the solar and heliospheric community to submit recent work that focusses on exploiting Solar Orbiter data. We encourage studies that connect activity at the Sun to what is measured in the solar wind using multiple data sets from Solar Orbiter. We are also interested in stand-alone studies using individual Solar Orbiter instruments and/or studies using other ground/space based solar observations that can help to answer the above goals. We also encourage theoretical and numerical studies that relate to the Sun, the solar wind, and the solar transients that can populate it.\N \N\N\N\N\NTopic: Solar\N\N

After two years of cruise phase, Solar Orbiter is now taking coordinated images of the Sun from closer than any spacecraft before along with measurements of the plasma environment that makes up the heliosphere. Using these combined observations, together with existing space and ground based solar and heliospheric measurements, scientists hope to find answers to some profound questions: What drives the Sun's 11-year cycle of rising and subsiding magnetic activity? What heats up the upper layer of its atmosphere, the corona, to millions of degrees Celsius? What drives the generation of the solar wind? What processes occur and modulate the solar wind as it expands through the heliosphere? What accelerates the solar wind to speeds of hundreds of kilometres per second? And how does it all affect our planet? This session aims to discuss these relevant scientific questions by inviting the solar and heliospheric community to submit recent work that focusses on exploiting Solar Orbiter data. We encourage studies that connect activity at the Sun to what is measured in the solar wind using multiple data sets from Solar Orbiter. We are also interested in stand-alone studies using individual Solar Orbiter instruments and/or studies using other ground/space based solar observations that can help to answer the above goals. We also encourage theoretical and numerical studies that relate to the Sun, the solar wind, and the solar transients that can populate it.

DESCRIPTION:Dr. Rowan Smith\NStar Formation in the Galactic Cradle\NTuesday 4th July 2023 @ 14h00\NStar forming clouds are not islands in and of themselves, but instead form out of, and are embedded within the interstellar medium of our Milky Way galaxy. Large scale galactic structure such as spiral arms, and clustered supernovae feedback from previous generations of star formation drive large scale turbulence which influences fragmentation within star forming clouds. Differential rotation within the disc stretches out large filaments of HI, within which molecular filaments are embedded. Magnetic fields generated by the large-scale dynamo thread the galaxy and influence the alignment of filamentary clouds and how they fragment. Thus, the history of star formation is intrinsically linked to the galactic environment in which it forms. However, star formation is almost always treated as a sub-grid process in galaxy simulations, while galaxy scale forces are neglected in studies of local star formation. In this talk I will use my own Cloud Factory simulations suite, as well as other results from the literature, to explore how star forming clouds and galaxies are linked, and the implications for our understanding of both.

Over the last decade a major change in our understanding of these objects have been enabled by the first sensitive hard (E> 10 keV) all sky x-ray surveys, followed up by detailed observations across the entire electromagnetic spectrum. I will briefly summarize some of a major changes in ourunderstanding of the nature of the host galaxies, the relationship to star formation, black hole mass, AGN fueling,and the implications for the theoretically predicted effect of feedback at low redshifts. I will examine the next steps in our understanding, stressing the soon to be launched XRISM x-ray spectroscopy mission and discuss the more distant future, focusing on the AXIS x-ray probe concept.

Key "Origins"
This key Origin session addresses the recent observational and theoretical developments regarding the early evolution of galaxies, focusing on the first 2 billion years of cosmic history. The main aim is to bring together experts to present and discuss recent insights on the following topics: - Detection and characterisation of the first stars and galaxies - Early metal enrichment and dust evolution in galaxies - Impact of reionization on star formation and the impact of galaxies on the reionization of the intergalactic medium - Morphological evolution: emergence of the first disk galaxies, size evolution and bulge formation - First quiescent galaxies and their implications for quenching processes - Growth of supermassive black holes and the feedback from AGN on early galaxy formation.

DESCRIPTION:Dr. Hannah Wakeford\NThe data and dynamics of exoplanet atmospheres\NWednesday 5th July 2023 @ 11h00\NExoplanet research has revolutionized our understanding of planetary systems beyond our own solar system. In particular, characterizing the atmospheres of exoplanets is crucial for determining the nature of their environment and tracing their formation history. In this talk, I will explore the latest exoplanet atmospheric characterization with Hubble and JWST from the UV to the mid-IR across a wide population of exoplanets. I will discuss the challenges in analysing the observations from systematics to chance events. I will also highlight the ways we interpret the spectra to understand the chemistry and dynamics of the atmosphere. I will finish with some of the most recent discoveries and future prospects for exoplanet atmospheric characterization.

Key "Origins"
Gravitational-wave astronomy has rapidly evolved into a leading and multi-disciplinary research field. UK-based science heavily contributes to this effort, with participation in the LIGO Scientific and Einstein Telescope Collaborations and the LISA, Pulsar Timing Array and Cosmic Explorer Consortia. Using the instruments pioneered by these groups, we expect to observe gravitational-waves extending from nanohertz to kilohertz frequencies.
The hertz to kilohertz end of the gravitational-wave spectrum is already being unveiled by the LIGO and Virgo detectors: close to 100 gravitational-wave candidates have been discovered. Although these signals span a discrete portion of the full gravitational-wave spectrum, they reveal much about binaries containing black holes and neutron stars: for example, they show structure in the black hole mass distribution, demonstrate that black holes have small spins, and confirm the connection between neutron-star collisions and kilonovae. The origin(s) of these binaries is an open question; various environments including the galactic field, star clusters and active galactic nuclei, have been proposed as possible explanations. Ground-based interferometers can also probe the origins of galaxies with studies investigating the properties of active galactic nuclei and searches for dark matter.

SUMMARY:[SME-PA] The dynamics of solar jets and associated eruptions

DESCRIPTION:\N\N\N\N\N\NThe dynamics of solar jets and associated eruptions\N \N\N\N\N\N\N\NOrganiser(s):\NSargam Mulay, Peter Wyper, Helen Mason\N \NSession type:\NRegular\N \NDescription:\N\N\N\NThe transfer of mass and energy within layers of the solar atmosphere and the heating of the solar corona is one of the key outstanding problems in solar physics. The Sun's magnetic field is known to play an important role in channelling and releasing energy. However, the detailed processes involved are still not fully understood, with both small-scale magnetic reconnection (nano-flares) and waves potentially playing a role. Understanding the physical mechanisms responsible for coronal heating and their core drivers is of crucial importance.\NIn this session, we focus on one manifestation of energy release, solar jets and associated eruptions.

The transfer of mass and energy within layers of the solar atmosphere and the heating of the solar corona is one of the key outstanding problems in solar physics. The Sun's magnetic field is known to play an important role in channelling and releasing energy. However, the detailed processes involved are still not fully understood, with both small-scale magnetic reconnection (nano-flares) and waves potentially playing a role. Understanding the physical mechanisms responsible for coronal heating and their core drivers is of crucial importance.
In this session, we focus on one manifestation of energy release, solar jets and associated eruptions. The transient and ubiquitous solar jets often exhibit a collimated flow of multithermal plasma and appear as an "Eiffel Tower" structure in all layers of the solar atmosphere.

These aspects have received significant attention over the last decade, with the combination of state-of-the-art observations and advanced modelling techniques proving paramount to our endeavours. With our sights now set on the forthcoming next generation facilities (e.g., DKIST, EST, ARCHER2, LUMI), it is an excellent opportunity to review our progress in preparation for the next decade. The aim of this session is to therefore bring together researchers from across the solar spectrum and discuss these recent advances in our understanding of coronal condensations: from coronal rain to prominences/filaments. A major goal of this session will be to isolate the current hurdles faced, envision potential solutions, and form concrete collaborations to follow such endeavours to fruition.\N\N\N\N \NTopic:\NSolar\N\N\N\N

Large UK owned facilities such as the William Herschel Telescope, the Isaac Newton Telescope and the Liverpool Telescope are now accompanied by an array of smaller, UK led projects such as SuperWASP and GOTO, and the UK community also exploits many of the other major facilities at the observatory via transnational access programmes and visiting instrumentation. The recent success of the HiPERCAM quintuple beam imager on the Spanish 10.4m GranTeCan is just one example of how UK interests stretch across the observatory.Over the next few years the capabilities of the UK facilities are changing significantly, providing exciting new opportunities to observers. The WEAVE instrument is currently being commissioned on the WHT. This powerful next-generation multi-fibre spectrograph will use 70% of the available time on the WHT over the next five years and will conduct eight major surveys covering studies of stellar evolution, Milky Way science, galaxy evolution and cosmology. Also currently under construction is the HARPS-3 instrument: the latest evolution of the hugely successful line of high resolution spectrographs which have had a huge impact in the field of radial velocity measurements of extrasolar planets. This will be commissioned on the INT to conduct a 10-year search for Earth sized planets around Sun-like stars, with 50% of the telescope time available for other PI-led science. The Liverpool Telescope will commission new instrumentation this year which will include an upgraded infrared imaging capability for the telescope, and 2026 will see first light for the New Robotic Telescope. This UK-led project is a 4-metre fully robotic successor to the Liverpool Telescope, with a science case focused on a rapid response to transient phenomena. Looking further ahead, UK institutions are participating in the construction of the Cherenkov Telescope Array and the European Solar Telescope: major international projects which will have a transformative impact on their fields. The purpose of this session is to bring together the development teams behind the new generation of instruments and facilities on La Palma with the observers who will exploit them in the decade to come. There will be a mix of technical and science talks. Telescope and instrument teams will be invited to present project updates and advertise the capabilities and observing modes which will be offered to the community. Science talks will be welcomed from current users of telescopes, as well as science discussions of programmes which will be enabled by the new instrumentation. We will also aim to identify synergies between the various UK facilities, capability gaps which could inspire future development, and opportunities for UK observers to better exploit transnational access programmes.\N \NTopic:\NFacilities

This session will be devoted to the origin of stars and star clusters, from the processes that assemble molecular clouds in galaxies, through the physical processes that convert this material into stars, to the statistical properties of stars, multiple systems and star clusters. There will be sub-sessions on the assembly and evolution of molecular clouds; the formation of filaments and cores; collapse and fragmentation and the genesis of low- and high-mass stars; measuring and explaining the Initial Mass Function and stellar multiplicity; the structure and dissolution of young star clusters; and next-generation instrumentation that will power future advances.

The programme will deliver a balance between the unprecedented observational insights being delivered by the full range of modern telescopes and interferometers, including GAIA, ALMA, JCMT, JWST and MeerKAT, and the numerical and theoretical advances facilitated by modern computer simulations and statistical techniques. We will present the latest results on the structure of the Galactic interstellar medium and its dynamics from kiloparsec to sub-parsec scales, impulsive triggering of star formation, feedback from both low- and high-mass stars, magneto-hydrodynamic simulations and the measurement of kinematics, magnetic fields and chemical abundances, as well as exploring the possibilities provided by future telecopes and facilities.

Key "Origins"
Gravitational-wave astronomy has rapidly evolved into a leading and multi-disciplinary research field. UK-based science heavily contributes to this effort, with participation in the LIGO Scientific and Einstein Telescope Collaborations and the LISA, Pulsar Timing Array and Cosmic Explorer Consortia. Using the instruments pioneered by these groups, we expect to observe gravitational-waves extending from nanohertz to kilohertz frequencies.
The hertz to kilohertz end of the gravitational-wave spectrum is already being unveiled by the LIGO and Virgo detectors: close to 100 gravitational-wave candidates have been discovered. Although these signals span a discrete portion of the full gravitational-wave spectrum, they reveal much about binaries containing black holes and neutron stars: for example, they show structure in the black hole mass distribution, demonstrate that black holes have small spins, and confirm the connection between neutron-star collisions and kilonovae. The origin(s) of these binaries is an open question; various environments including the galactic field, star clusters and active galactic nuclei, have been proposed as possible explanations. Ground-based interferometers can also probe the origins of galaxies with studies investigating the properties of active galactic nuclei and searches for dark matter. The instruments continue to undergo upgrades to reduce the impact of noise, meaning that the fourth gravitational-wave observing run should yield daily detections and the potential for discovery of new source types. A growing catalogue will yield independent and precise constraints on the neutron star equation of state, the Hubble constant and the star formation rate.
The millihertz region of the gravitational-wave spectrum will be analysed by future space-borne detectors including LISA, allowing the detection of thousands of gravitational-wave sources: massive black-hole mergers, extreme mass-ratio inspirals, millions of galactic binaries, and more.

DESCRIPTION:\N\N\N\NAGN demographics and evolution in the era of large-scale surveys\N \N\N\N\N\N\N\NOrganiser(s): \NIzzy Garland (co-chair), David Alexander (co-chair), Rebecca Canning, Sotiria Fotopoulou, Carolin Villforth, James Aird, Cassandra Barlow-Hall, Jack Delaney, Vicky Fawcett, David O'Ryan, Maddie Silcock, Brooke Simmons, Matthew Thorne\N \NSession type:\NRegular\N\N\N\N\N \N Description: \NGreat progress has been made on the demographics and co-evolution of AGN since the turn of the millennium, greatly enhanced by multi-object spectroscopic follow-up observations of AGN selected over a range of wavelengths (e.g., X-ray, optical, IR, and radio). Large-scale surveys such as SDSS already provide robust optically selected AGN samples of 10,000s - 100,000s, allowing researchers to place AGN within the broader galaxy and large-scale environments, and follow-up programmes started/planned with DESI, WEAVE, 4MOST, MOONS, and Euclid will push to yet fainter sensitivities with larger samples. This great explosion of data is already providing us with an unprecedented census of the AGN population, and allowing us to track their demographics and properties across cosmic time, with spectroscopically identified samples numbering in the millions.From a plethora of studies over the last decade it has become clear that AGN co-evolve with their host galaxies. To develop a more complete picture of galaxy evolution it is therefore vital that we understand what triggers the AGN phase of a supermassive black hole’s existence, and how AGN fuelling and feedback affect the host galaxy. Thanks to observations of a range of galaxy morphologies, it is clear that this co-evolution can occur both via merger-driven and merger-free pathways. Whilst less is known about the merger-free mechanism, we know that this pathway dominates black hole growth. However, this is difficult to observe, since galaxies with a completely merger-free history spanning at least the lifetime of their AGN are not common.This session will discuss AGN from a range of viewpoints, including their co-evolution with their host galaxies, studies at different wavelengths, the potential of new and upcoming facilities and surveys, the promise of machine learning techniques to deal with the vast new datasets, and new theoretical developments. Amongst the questions that we hope to answer are: What are the galactic and large-scale environments of AGN and how do these change as a function of redshift, mass, luminosity, mass-accretion rate, etc? Which pathways exist to facilitate co-evolution between galaxies and black holes? How complete is our cosmic AGN census, when combining new spectroscopic measurements with multi-wavelength signatures?

Great progress has been made on the demographics and co-evolution of AGN since the turn of the millennium, greatly enhanced by multi-object spectroscopic follow-up observations of AGN selected over a range of wavelengths (e.g., X-ray, optical, IR, and radio). Large-scale surveys such as SDSS already provide robust optically selected AGN samples of 10,000s - 100,000s, allowing researchers to place AGN within the broader galaxy and large-scale environments, and follow-up programmes started/planned with DESI, WEAVE, 4MOST, MOONS, and Euclid will push to yet fainter sensitivities with larger samples. This great explosion of data is already providing us with an unprecedented census of the AGN population, and allowing us to track their demographics and properties across cosmic time, with spectroscopically identified samples numbering in the millions.
From a plethora of studies over the last decade it has become clear that AGN co-evolve with their host galaxies. To develop a more complete picture of galaxy evolution it is therefore vital that we understand what triggers the AGN phase of a supermassive black hole’s existence, and how AGN fuelling and feedback affect the host galaxy. Thanks to observations of a range of galaxy morphologies, it is clear that this co-evolution can occur both via merger-driven and merger-free pathways. Whilst less is known about the merger-free mechanism, we know that this pathway dominates black hole growth. However, this is difficult to observe, since galaxies with a completely merger-free history spanning at least the lifetime of their AGN are not common.
This session will discuss AGN from a range of viewpoints, including their co-evolution with their host galaxies, studies at different wavelengths, the potential of new and upcoming facilities and surveys, the promise of machine learning techniques to deal with the vast new datasets, and new theoretical developments. Amongst the questions that we hope to answer are: What are the galactic and large-scale environments of AGN and how do these change as a function of redshift, mass, luminosity, mass-accretion rate, etc? Which pathways exist to facilitate co-evolution between galaxies and black holes? How complete is our cosmic AGN census, when combining new spectroscopic measurements with multi-wavelength signatures? What effective methods and techniques can we use to analyse and interpret the vast datasets? Overall, we aim to review progress made over the last decade, and to plan for the effective exploitation of the data from upcoming facilities.

SUMMARY:[CSL] Gravitational Waves (D)
CREATED:20230419T133455Z
DTSTAMP:20230419T133455Z
DESCRIPTION:\N\N\N\NGravitational Waves: From compact-object mergers to the origins of the early universe (and everything in-between)\N\N\N\N\N\N\N \NOrganiser(s): Jean-Baptiste Bayle, Tjarda Boekholt, Paul Brook, Debatri Chattopadhyay, Gareth Cabourn Davies, Alexandre Gottel, Charlie Hoy, Ali James, Hannah Middleton, Isobel Romero-Shaw\N\N\N\N\N \NSession type: Key "Origins"\N\N\N\N\N \NDescription: Gravitational-wave astronomy has rapidly evolved into a leading and multi-disciplinary research field. UK-based science heavily contributes to this effort, with participation in the LIGO Scientific and Einstein Telescope Collaborations and the LISA, Pulsar Timing Array and Cosmic Explorer Consortia. Using the instruments pioneered by these groups, we expect to observe gravitational-waves extending from nanohertz to kilohertz frequencies.The hertz to kilohertz end of the gravitational-wave spectrum is already being unveiled by the LIGO and Virgo detectors: close to 100 gravitational-wave candidates have been discovered. Although these signals span a discrete portion of the full gravitational-wave spectrum, they reveal much about binaries containing black holes and neutron stars: for example, they show structure in the black hole mass distribution, demonstrate that black holes have small spins, and confirm the connection between neutron-star collisions and kilonovae. The origin(s) of these binaries is an open question; various environments including the galactic field, star clusters and active galactic nuclei, have been proposed as possible explanations. Ground-based interferometers can also probe the origins of galaxies with studies investigating the properties of active galactic nuclei and searches for dark matter. The instruments continue to undergo upgrades to reduce the impact of noise, meaning that the fourth gravitational-wave observing run should yield daily detections and the potential for discovery of new source types. A growing catalogue will yield independent and precise constraints on the neutron star equation of state, the Hubble constant and the star formation rate.The millihertz region of the gravitational-wave spectrum will be analysed by future space-borne detectors including LISA, allowing the detection of thousands of gravitational-wave sources: massive black-hole mergers, extreme mass-ratio inspirals, millions of galactic binaries, and more. These detections will enhance our understanding of stellar and early galaxy evolution, the growth and merger history of massive black holes, and probe the rate of expansion of the Universe. LISA will undergo adoption review by ESA this year and is due to launch in the early 2030s. Still, many challenges in instrumentation and data analysis must be solved before LISA flies. LISA Data Challenges function as a call to test algorithms that will answer numerous questions on black-hole astrophysics, galaxy formation, cosmology, and tests of general relativity. Pulsar timing arrays seek to detect nanohertz gravitational-wave signals created by the most massive black holes in the Universe. The pulsar timing array consortia have seen speculative hints of a first detection, and further results are expected this year: the ever-expanding pulsar population and longer observation spans give rise to increasingly sensitive data. There is much to be discovered, including insights into the formation and evolution of massive black hole binaries and their host galaxies.

Key "Origins"
Gravitational-wave astronomy has rapidly evolved into a leading and multi-disciplinary research field. UK-based science heavily contributes to this effort, with participation in the LIGO Scientific and Einstein Telescope Collaborations and the LISA, Pulsar Timing Array and Cosmic Explorer Consortia. Using the instruments pioneered by these groups, we expect to observe gravitational-waves extending from nanohertz to kilohertz frequencies.
The hertz to kilohertz end of the gravitational-wave spectrum is already being unveiled by the LIGO and Virgo detectors: close to 100 gravitational-wave candidates have been discovered. Although these signals span a discrete portion of the full gravitational-wave spectrum, they reveal much about binaries containing black holes and neutron stars: for example, they show structure in the black hole mass distribution, demonstrate that black holes have small spins, and confirm the connection between neutron-star collisions and kilonovae. The origin(s) of these binaries is an open question; various environments including the galactic field, star clusters and active galactic nuclei, have been proposed as possible explanations. Ground-based interferometers can also probe the origins of galaxies with studies investigating the properties of active galactic nuclei and searches for dark matter. The instruments continue to undergo upgrades to reduce the impact of noise, meaning that the fourth gravitational-wave observing run should yield daily detections and the potential for discovery of new source types. A growing catalogue will yield independent and precise constraints on the neutron star equation of state, the Hubble constant and the star formation rate.
The millihertz region of the gravitational-wave spectrum will be analysed by future space-borne detectors including LISA, allowing the detection of thousands of gravitational-wave sources: massive black-hole mergers, extreme mass-ratio inspirals, millions of galactic binaries, and more. These detections will enhance our understanding of stellar and early galaxy evolution, the growth and merger history of massive black holes, and probe the rate of expansion of the Universe. LISA will undergo adoption review by ESA this year and is due to launch in the early 2030s. Still, many challenges in instrumentation and data analysis must be solved before LISA flies. LISA Data Challenges function as a call to test algorithms that will answer numerous questions on black-hole astrophysics, galaxy formation, cosmology, and tests of general relativity.
Pulsar timing arrays seek to detect nanohertz gravitational-wave signals created by the most massive black holes in the Universe. The pulsar timing array consortia have seen speculative hints of a first detection, and further results are expected this year: the ever-expanding pulsar population and longer observation spans give rise to increasingly sensitive data. There is much to be discovered, including insights into the formation and evolution of massive black hole binaries and their host galaxies. New facilities such as the SKA are expected to be transformative.
These sessions address all areas of astronomy and astrophysics that are affected by gravitational-wave observations, as well as the potential of multi-messenger work. This includes electromagnetic counterparts, cosmic rays, supernovae, extragalactic neutrinos, and more. Anyone whose research is related to gravitational-wave science is encouraged to submit an abstract.

Key "Origins"
Gravitational-wave astronomy has rapidly evolved into a leading and multi-disciplinary research field. UK-based science heavily contributes to this effort, with participation in the LIGO Scientific and Einstein Telescope Collaborations and the LISA, Pulsar Timing Array and Cosmic Explorer Consortia. Using the instruments pioneered by these groups, we expect to observe gravitational-waves extending from nanohertz to kilohertz frequencies.
The hertz to kilohertz end of the gravitational-wave spectrum is already being unveiled by the LIGO and Virgo detectors: close to 100 gravitational-wave candidates have been discovered. Although these signals span a discrete portion of the full gravitational-wave spectrum, they reveal much about binaries containing black holes and neutron stars: for example, they show structure in the black hole mass distribution, demonstrate that black holes have small spins, and confirm the connection between neutron-star collisions and kilonovae. The origin(s) of these binaries is an open question; various environments including the galactic field, star clusters and active galactic nuclei, have been proposed as possible explanations. Ground-based interferometers can also probe the origins of galaxies with studies investigating the properties of active galactic nuclei and searches for dark matter. The instruments continue to undergo upgrades to reduce the impact of noise, meaning that the fourth gravitational-wave observing run should yield daily detections and the potential for discovery of new source types. A growing catalogue will yield independent and precise constraints on the neutron star equation of state, the Hubble constant and the star formation rate.
The millihertz region of the gravitational-wave spectrum will be analysed by future space-borne detectors including LISA, allowing the detection of thousands of gravitational-wave sources: massive black-hole mergers, extreme mass-ratio inspirals, millions of galactic binaries, and more. These detections will enhance our understanding of stellar and early galaxy evolution, the growth and merger history of massive black holes, and probe the rate of expansion of the Universe.

These sessions address all areas of astronomy and astrophysics that are affected by gravitational-wave observations, as well as the potential of multi-messenger work. This includes electromagnetic counterparts, cosmic rays, supernovae, extragalactic neutrinos, and more.

These detections will enhance our understanding of stellar and early galaxy evolution, the growth and merger history of massive black holes, and probe the rate of expansion of the Universe. LISA will undergo adoption review by ESA this year and is due to launch in the early 2030s. Still, many challenges in instrumentation and data analysis must be solved before LISA flies. LISA Data Challenges function as a call to test algorithms that will answer numerous questions on black-hole astrophysics, galaxy formation, cosmology, and tests of general relativity. Pulsar timing arrays seek to detect nanohertz gravitational-wave signals created by the most massive black holes in the Universe. The pulsar timing array consortia have seen speculative hints of a first detection, and further results are expected this year: the ever-expanding pulsar population and longer observation spans give rise to increasingly sensitive data. There is much to be discovered, including insights into the formation and evolution of massive black hole binaries and their host galaxies. New facilities such as the SKA are expected to be transformative.These sessions address all areas of astronomy and astrophysics that are affected by gravitational-wave observations, as well as the potential of multi-messenger work. This includes electromagnetic counterparts, cosmic rays, supernovae, extragalactic neutrinos, and more. Anyone whose research is related to gravitational-wave science is encouraged to submit an abstract.\N\N\N\N\N \NTopic: Transients\N \N\NThis session is sponsored by:\N\N\N\N

Key "Origins"
Gravitational-wave astronomy has rapidly evolved into a leading and multi-disciplinary research field. UK-based science heavily contributes to this effort, with participation in the LIGO Scientific and Einstein Telescope Collaborations and the LISA, Pulsar Timing Array and Cosmic Explorer Consortia. Using the instruments pioneered by these groups, we expect to observe gravitational-waves extending from nanohertz to kilohertz frequencies.
The hertz to kilohertz end of the gravitational-wave spectrum is already being unveiled by the LIGO and Virgo detectors: close to 100 gravitational-wave candidates have been discovered. Although these signals span a discrete portion of the full gravitational-wave spectrum, they reveal much about binaries containing black holes and neutron stars: for example, they show structure in the black hole mass distribution, demonstrate that black holes have small spins, and confirm the connection between neutron-star collisions and kilonovae.

The millihertz region of the gravitational-wave spectrum will be analysed by future space-borne detectors including LISA, allowing the detection of thousands of gravitational-wave sources: massive black-hole mergers, extreme mass-ratio inspirals, millions of galactic binaries, and more. These detections will enhance our understanding of stellar and early galaxy evolution, the growth and merger history of massive black holes, and probe the rate of expansion of the Universe. LISA will undergo adoption review by ESA this year and is due to launch in the early 2030s. Still, many challenges in instrumentation and data analysis must be solved before LISA flies. LISA Data Challenges function as a call to test algorithms that will answer numerous questions on black-hole astrophysics, galaxy formation, cosmology, and tests of general relativity.
Pulsar timing arrays seek to detect nanohertz gravitational-wave signals created by the most massive black holes in the Universe. The pulsar timing array consortia have seen speculative hints of a first detection, and further results are expected this year: the ever-expanding pulsar population and longer observation spans give rise to increasingly sensitive data. There is much to be discovered, including insights into the formation and evolution of massive black hole binaries and their host galaxies. New facilities such as the SKA are expected to be transformative.
These sessions address all areas of astronomy and astrophysics that are affected by gravitational-wave observations, as well as the potential of multi-messenger work. This includes electromagnetic counterparts, cosmic rays, supernovae, extragalactic neutrinos, and more. Anyone whose research is related to gravitational-wave science is encouraged to submit an abstract.
