Conferences and Meetings on Astronomy, Astrophysics and Cosmology

Kavli Institute for Theoretical Physics (KITP)

The circumgalactic medium (CGM) can be viewed as an atmosphere that surrounds a galaxy and sustains star formation within it. Much of what we know about the CGM has come from absorption-line spectroscopy, mainly in the UV band, of gas at temperatures below the galaxy's virial temperature. A comparable amount of hotter gas, closer to the virial temperature, may also be present but has been harder to detect. If it is there, then the properties of the cooler clouds and the hotter ambient medium are likely to be complementary, deeply interwoven, and physically complex. It follows that the physics of cosmic rays, magnetic fields, turbulent mixing layers, conductive interfaces, and shocks may then play a leading role in setting the fate of the multiphase CGM. This conference will examine the evidence for a virial-temperature component along with the observations capable of revealing its properties and its relationship to the cooler components. Probes that complement UV absorption-line observations will be emphasized, including X-ray emission and absorption, UV and optical emission, Sunyaev-Zel'dovich probes, Fast Radio Bursts, and signposts of non-thermal particle acceleration.

The CAP conference will have a virtual edition in 2021.

What could be a bigger source of "big data" than the entire Universe? Researchers in statistics and computer science are developing new methods to analyse the "big data" that companies and governments want to understand. To test out these methods they need big datasets that everyone can share - and new astronomical telescopes just happen to be gearing up to generate observations of billions of stars and galaxies that fit the bill. Insights from statistics will help astrophysicists to get the most out of these observations. The Astrostatistics 2021 workshop will bring together statisticians and astrophysicists to learn the technical languages of the two fields and identify how to work together to combine the excitement of space with big data.

Astrometric, photometric and spectroscopic all-sky surveys provide the first complete, unbiased view of the Galactic population of the most abundant type of stellar remnants: white dwarfs. This wealth of observational data provides an array of opportunities to use white dwarfs as probes of a wide range of astrophysics, including the formation and evolution of stars and planets, the star formation rate of the Galaxy, and the populations of low-frequency gravitational wave sources and progenitors of thermonuclear supernovae. These applications require improved models of these electron-degenerate stars, which in turn rely on developments in the relevant input physics, including equations of state and opacities. This conference will provide a joint platform for experts in the observational and theoretical study of white dwarfs, scientists working on the underlying fundamental physics, and astronomers using white dwarfs as diagnostic tools to gain a panoramic overview of the state-of-the-art, to identify remaining limitations of the current models, and to explore novel scientific opportunities arising from the new data.

The vast majority of stars in our galaxy will eventually stop burning nuclear fuel and slowly cool as very dense spheres of gas, with radii of only ~7000 km (similar to Earth's radius). These “white dwarfs” (WDs) are the most common endpoint of stellar evolution. They play a central role in many areas of astrophysics, ranging from the study of exoplanets to thermonuclear supernovae, the type of explosions used to measure the expansion rate of our Universe. Recent observational probes by the Gaia, Kepler, and TESS satellites have gifted the astrophysics community with an incredibly rich dataset that is propelling our understanding of these objects. Old questions have been answered and new puzzles have emerged. How do these objects cool? Are their interiors liquid or solid? What happens when two WDs merge? Which planets survive the metamorphosis of their host stars into WDs? In this conference, we will answer some of these questions and explore ways to bring this exciting new astrophysics to the classroom.

Radioactive nuclei play a significant role in many current astrophysical pursuits, from the origin of the elements to the driving of emissions from supernovae (56Ni) and kilonovae (r-process radioactivity). Radioactive nuclei are crucial for direct studies of galactic enrichment (7Be, 26Al, 44Ti, 60Fe, 99Tc, 244Pu) and stellar explosions (56Ni, 44Ti). Stars and their explosions, galaxies and their evolving interstellar medium, and the origin of the solar system are among the targeted astrophysical objects. Stardust, meteorites, ocean floor deposits, cosmic-rays, and gamma-ray spectroscopy provide a rich variety of astronomy to exploit the inherent power of radioactivity. Investigation tools range from numerical models, astronomical instrumentation, and laboratory experiments to derive material compositions and nuclear reaction rates. The aim of the conference is to bring together researchers from all these different fields to promote interaction through the common ground of radioactivity.

One of the central features of the AAS Summer and Winter Meetings is their plenary talks spanning the full breadth of astrophysics. Some plenaries are given by prize winners from the AAS and other organizations, while other speakers are selected by the AAS Vice Presidents. Most plenary talks present science content, but talks on the state of the profession, demographics, and societal issues of relevance to the astronomical community are also regularly scheduled.

The goal of these Workshops is to offer the physics community a significant opportunity to assess the status of major topics within the field and initiate collaborative efforts to address current challenges. The Workshops attract leading experimentalists and theorists, from all over the world, allowing them to exchange ideas and to develop new strategies. In many cases the efforts initiated at these Workshops result in completed projects that are published in international journals. These projects have sometimes proven to be major breakthroughs such as the MSW effect, which was first discussed at the WIN85 meeting in Finland.

This conference will celebrate the career of Lee Hartmann, who has made enormous contributions to our field during his productive life. For over 3 decades Lee has been a leading pioneer in characterizing the physics of molecular clouds, stars and planet formation. His scientific breadth and impact can be seen in his studies on molecular cloud formation and cloud lifetimes. This has led to a change in our paradigm of star formation towards more rapid evolution. He has been among the first to recognize the importance of accretion and magnetic fields in the phenomena observed in young stars, and has led ground-breaking efforts characterizing these effects. As a tribute to Lee, but also recognizing that we stand on the threshold of a new era with the arrival of JWST, E-ELT and SKA, it is appropriate to take stock of the most fascinating developments in our field, emphasizing those areas where Lee has made significant contributions.

Gravitational-waves are a new way to explore the sky and uncover the Universe’s deepest mysteries. Although the first detection of these "ripples of space-time" is only a few years old, scientists can now harness the potential of gravitational waves in testing Einstein’s General Relativity theory under extreme conditions, helping to understand the origin of matter, and measuring the evolution of the Universe. Researchers from all around the world are gathering in Oaxaca to discuss recent progress in, and the future of gravitational-wave science. The workshop "Detection and analysis of gravitational waves in the era of multi-messenger astronomy: From mathematical modelling to machine learning", provides a forum, unique in its genre, for discussing new mathematical methods in modelling, detecting, and analyzing gravitational waves, as well as their integration with machine learning, or artificial intelligence.

Many of the largest uncertainties in the physics of stars are related to transport in their interiors, including the transport of heat, chemical elements, and angular momentum. Our current understanding of these processes has been challenged and refined by recent advances in observational data, including TESS and spectroscopic studies, by new work on 1D models, and by the ability to generate more sophisticated 3D simulations. This conference will bring together members of the community working on transport processes from a variety of angles, including observations, theoretical calculations, and stellar models, with an emphasis on how these techniques can be combined to improve our understanding of stellar physics.

Binary systems are ubiquitous in nature, from stars to the supermassive black holes expected to reside in galactic nuclei. In many circumstances, the binary system is enveloped by circumbinary gas. How does circumbinary gas evolve and influence the embedded binary? What observational signatures of this gas are most informative? What novel numerical techniques must we deploy to better model these systems? This conference will bring together two distinct communities: those working on massive black hole binaries with those working on stellar binaries. Because recent years have seen remarkable progress in observations of stellar binaries, and numerical modeling of both stars and black holes, now is the ideal time to bring together these two groups. The conference will highlight the remarkable similarities of problems at such varied astrophysical scales, and shed light on the crucial next steps for pushing the boundaries of our knowledge.

The goal of this conference is to survey the interdisciplinary avenues in modern neutrino physics, with a threefold overarching set of aims: (1) to maximize the new physics potential of present and upcoming experimental data, (2) to understand new directions in the quest for high-precision neutrino cross sections, including synergy with lattice QCD; and, (3) to ensure that the impact of neutrinos on astrophysical and cosmological processes is comprehensively addressed. Particular attention will be given to exploring connections between neutrinos and gravitational waves, cosmological data, sources for IceCube’s astrophysical neutrino events, implications of the latest sterile searches for cosmology and astrophysics, and an assessment of the role of the neutrino detectors as astrophysical observatories.

UC Santa Barbara, Kavli Institute for Theoretical Physics (KITP)

The detection of gravitational waves by Advanced LIGO/Virgo has opened a new frontier in physics, with impact on areas ranging from field theory through stellar evolution and cosmology. It has also seeded new connections between theoretical communities, especially between field theorists and classical relativists. An even brighter future lies ahead, with more sensitive ground-based detectors and, eventually, a space-based observatory. Current and future experiments demand precision modelling of gravitational-wave signals in order to interpret the strongest gravitational-wave events and to enable sensitive searches for new physics which may be embedded in these signals. The conference will bring together experts from three communities: classical relativity, effective field theory, and scattering amplitudes. Building on the current state of the art, we will discuss the needs of the next generation of gravitational-wave experiments; identify which challenges theory must overcome; highlight recent advances in gravitational wave modelling for more detailed study; and uncover the most promising emerging tools and techniques from classical and quantum field theory for further development.
