Astronomy at the beginning of the 21st century, and particularly research arising from wide-field survey observatories at various wavebands, finds itself with serious challenges in statistical treatments of data to achieve its astrophysical goals. A vast range of statistical problems arise in the scientific interpretation of astronomical studies involving sampling, multivariate and survival analysis, image and spatial analysis, signal processing and time series analysis, nonlinear regression, and more. It is this diversity of statistical issues confronting astronomy today that led to the creation of the Center for Astrostatistics at Penn State in 2003 to facilitate development and promulgation of statistical expertise and toolkits for astronomy and related observational sciences.

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.

VLTI schools of interferometry have been organized roughly every two years since the opening of ESO Very Large Telescope Interferometer in 2002. They have helped to train hundreds of astrophysicists in using interferometry and the instruments at VLTI and other facilities for their research. The aim of these VLTI schools is to offer Ph.D. students, post-doctoral and permanent researchers an introduction to the technique of long-baseline optical/infrared interferometry, an overview of the current generation of instruments, and lectures and practice sessions in data reduction, modelling and image reconstruction. Seminars and reviews on astrophysical results in various fields ranging from stellar physics to planetology and extra-galactic science are also given.

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.

The aim of this conference is discuss the beginnings and formation of the largest gravitationally-bound structures in the Universe.

Energetic and collimated beams of plasma launched from the centre of galaxies have fascinated the community for a century. In spite of the advancement in observational and theoretical modelling techniques, many aspects regarding the detailed physics of extra-galactic jets remain not fully understood. This conference aims to push forward our understanding of extra-galactic jets bringing together experts from theory and observations. The main focus shall be on the theoretical side. One major aim of this conference is to demonstrate recent advances in the multi-scale numerical modeling of jets and to discuss strategies for how to better constrain simulations with multi-wavelength and high-resolution observational data. Another focus shall be the universality of jet properties and understand what we can learn from other jets sources such as non-relativistic jets or GRBs.

The nature and composition of Dark Matter and Dark Energy are two of the most pressing mysteries of frontier physics, and research in these fields is presently gathering increasing momentum and attracting the efforts of scientists from many international institutions. The "16th Patras Workshop on Axions WIMPs and WISPs” is the latest event in an annual series of conferences, started in 2005 at CERN. This workshop is aiming to continue the rich and successful series, reviewing recent theoretical advances, laboratory experiments, novel ideas as well as astrophysical and cosmological results in the fields of axions, WIMPs and WISPs. Participation by young scientists is strongly encouraged.

The study of the highest-redshift galaxies and quasars is critical to our comprehension of how early galaxies helped shape the Universe as we see it today. In particular the properties of the interstellar medium (ISM) of these galaxies provide important clues towards understanding the complex interplay between the accretion of baryons onto galaxies, the physics that drives the buildup of stars out of this gas, the subsequent chemical evolution and feedback processes, and the reionization of the Universe. The Atacama Large Millimeter/submillimeter Array (ALMA) continues to play a fundamental, groundbreaking role in the characterisation of the ISM of high-redshift galaxies. Observations of the dust continuum emission, atomic fine-structure and molecular lines arising from high-redshift galaxies are now carried out routinely, providing ever more constraints on the theoretical models of galaxy formation and evolution in the early Universe. The aim of this symposium is to bring together the observational and theoretical high-redshift ALMA communities in order to discuss the most recent results in the rapidly evolving field of galaxies at redshift z~4 and above. This symposium also aims to explore future synergies between ALMA and the Extremely Large Telescope (ELT), one of the future flagships of European Astronomy, for high-redshift science.

The CHEOPS workshop IV will be held 13-16 July, 2021, some 15 months after the beginning of CHEOPS science operations. The workshop will be the occasion for the planetary science community at large to discuss and share the first main results of CHEOPS in different fields, from the planetary internal structure to atmospheric characterization, etc. Participants are invited to propose contributed talks and posters on all scientific aspects linked to CHEOPS, including CHEOPS based-results as well as proposals for future observations and synergies with other facilities.

This international school will offer an overview of the observational constraints, the interpretative tools and the theoretical frameworks used for studying the interstellar medium in galaxies from the epoch of reionization to the Milky Way. Furthermore, it aims to build a synergy between the Galactic ISM and extragalactic communities. Time will be devoted to discussion between participants and lecturers, with the hope of kick-starting original projects.

The 2021 Sagan Summer Workshop will focus on young planets and the circumstellar disks from which they form during the first few million years of a star's lifetime. As a protoplanet accretes material from the disk, dynamical interactions drive migration and produce disk substructures such as the gaps, rings and spirals now detected in high-resolution optical, near-infrared, and submillimeter images. Over the next 100 million years, planetary systems continue to evolve through processes such as collisions, differentiation, and scattering. These late-epoch evolutionary processes are reflected in the structure and distribution of secondary dust disks. These debris disks, formed as the result of planetesimals stirring, serve as signposts for the presence of planetary systems.

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.

The observational evidence for the acceleration of the universe shows that our canonical theories of cosmology and fundamental physics are at least incomplete, and possibly incorrect: new physics is out there, waiting to be discovered. Key cosmological paradigms like dark matter, dark energy, inflation and neutrino masses, all of which require new physics, will leave imprints on a range of astrophysical scales. Thus progress in fundamental physics will increasingly rely on progress in observational astrophysics and cosmology.

Computational relativistic astrophysics and numerical relativity face a number of challenges following the first detection of binary black holes and binary neutron stars: high Lorentz factors, strong and dynamical gravitational fields, uncertain equations of state, magnetic fields, radiative and dissipative effects, large dynamical ranges, solutions of constrained hyperbolic systems. The likely gravitational signals produced after the collapse of massive stellar cores offer unique probes of the dynamics of newly-born compact stellar remnants. Predicting source dynamics of future detections of gravitational wave signals is important to understand the physics of these events in the current and next-generation earth-based gravitational-wave detectors and essential to achieve design sensitivity in future space-based detectors. The goal of this workshop is to bring together mathematical modelers in general relativity, astrophysicists, and experts in numerical relativity to discuss open issues to improve current approaches to build increasingly more accurate gravitational wave templates that allow to identify future detections.

Ever since general relativity’s birth in 1915, mathematics has had a profound impact on the way the theory has been understood: Examples over the years include Hilbert’s variational formulation, Noether’s early theorems on conservation laws, Choquet-Bruhat’s foundational well-posedness theorem and the hyperbolicity of the equations, Bondi’s concept of null infinity and gravitational waves, the incompleteness theorems of Penrose and the black hole concept, the positive energy theorem of Schoen and Yau, and the nonlinear stability of Minkowski space proven by Christodoulou and Klainerman. In more recent years, the power of numerics has added additional insights to our mathematical picture, particularly after Pretorius’s 2004 breakthrough allowing for the numerical simulation of binary black hole systems. Today, research on mathematical and numerical aspects of general relativity constitute two vibrant fields which have become very influential in the wider mathematics and physics communities. The two fields have many points of contact: Some common goals shared by both rigorous mathematical analysis and numerics include understanding the formation of black holes in gravitational collapse, their non-linear stability, and their interaction with other black holes in binary systems or other scattering processes. In their practical application to astrophysics, the two fields often play complementary roles: Numerics generates the templates which play an important part in interpreting gravitational wave detections by LIGO and VIRGO, while rigorous mathematical analysis has introduced subtle new concepts, like Christodoulou memory, which may play an important role in the next generation of detectors. Another common goal of both rigorous mathematics and of numerics, of interest to theoretical physics, is to understand generic spacetime singularities, so as to resolve in particular the celebrated weak and strong cosmic censorship conjectures of Penrose. As singularities probe the limits of the theory, a resolution of these conjectures may shed light on various attempts to transcend general relativity. Other recent problems which have brought together mathematics and numerics include work on asymptotically anti-de Sitter spacetimes, and well-posedness for alternative theories of gravity, both of interest in high energy physics. There is also recent activity on inverse problems. This workshop will gather mathematicians, theoretical physicists and numerical analysis developers to discuss these and other issues.

A proper understanding of stellar evolution and of the chemical make-up of the building blocks in the Universe near and far cannot be achieved without a detailed understanding of the wind physics during the late stages of stellar evolution as a function of the cosmic environment and hence metallicity. The goal of this IAU Symposium 366 is to propel our understanding of stellar wind physics across stellar mass by bringing together the scientific communities which often focus on either the low-mass or the massive stars. This cross-disciplinary approach will fuel new scientific ideas and insights and will facilitate for new collaborations to grow across communities.

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.

Gravitational-wave (GW) observations offer a unique opportunity to study astrophysical and cosmological sources that are difficult to access through electromagnetic observations. Inferring the sources’ properties from their GW signal is one of the key objectives of GW data analysis. The planned improvements in the sensitivity of the ground-based detectors and future space-based observatories, however, bring unique computational and mathematical challenges to the inference problem including long-duration signals, high signal-to-noise ratios, increased parameter dimensionality and overlapping signals. These challenges must be overcome to fully exploit the scientific potential of GW observations. The goal of this workshop is to connect statisticians, computer scientists and GW astrophysicists to discuss the current state-of-the-art approaches to parameter estimation in GW astrophysics, and to identify the open issues to enable fast and reliable inference for different GW sources, including modelled and un-modelled signals, for the current and planned GW observatories.

Detection of gravitational waves requires the operation of very sophisticated detectors producing large amounts of data. The sensitivity of the gravitational-wave detectors to astrophysical signals is limited by the noise associated with the instruments themselves and their environment. Invaluable astrophysical information is buried in data sets that may be too large or complex to be analyzed with traditional data-processing techniques. To make the analysis of gravitational-wave detector data more efficient it becomes increasingly more important to characterize and mitigate the detector noise sources, as well as find more powerful ways to extract information from the detector data. Methods for the analysis of gravitational-wave detector data range from standard signal processing algorithms to novel machine learning algorithms. This workshop will focus on the development of these techniques for a more efficient handling of gravitational-wave data sets, reduction of detector noise, identification of astrophysical signals and increase in detection confidence. It will bring together astrophysicists, mathematicians and statisticians working on the state-of-the-art data analysis.

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.

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.

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.

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.

The Torino Workshops series started in Torino in 1995. Since then, 12 workshops have been held by various institutions around the world. Traditionally, the Torino Workshop focuses on the physics of asymptotic giant branch (AGB) stars and many related topics: stellar evolution and nucleosynthesis, observations (photometry, spectrometry, and asteroseismology), stellar winds, dust and presolar grain formation, galactic chemical evolution, theoretical and experimental nuclear astrophysics. The workshop will bring together experts, and friends, involved in these research fields to identify current key scientific questions and the possible ways to address them by interdisciplinary approaches. This meeting edition will celebrate Prof. Maurizio M. Busso on the occasion of his 70th birthday. Maurizio is among the founders of the Torino Workshop and during his career he has given important contributions to the study of AGB stars and related fields covered in the workshop.

Asteroseismology in the Era of Surveys from Space and the Ground: Stars, Planets, and the Milky Way

Asteroseismology is a young and rapidly developing field in stellar astrophysics. It enables efficient probes of stellar interiors and provides critical input to many fields in contemporary astrophysics. Being very sensitive to the total time span and precision of individual stellar brightness measurements, observational asteroseismology has experienced significant boosts with the launch of space-missions such as CoRoT, Kepler/K2, and TESS. The interior macro- and micro-physics are being probed with unprecedented precision for isolated stars, as well as small- to intermediate-sized stellar populations across the entire HR-diagram. Powerful synergies between asteroseismology and fields such as binary stars, exoplanets, clusters, galactic archeology, are emerging fast. In this joint 6th/13th in a series of TASC/KASC workshops, we aim to put asteroseismology in a wider context, reaching out to other fields in astrophysics, focusing on the above synergies with specific attention to joint exploitation of large-scale space- and ground-based surveys. We will celebrate the 10th anniversary of “Kepler Asteroseismology in Action” started during KASC3 at Aarhus University, where Kepler asteroseismology was put into practice for the first time, opening a new horizon for observational asteroseismology as we know it today. KASC6/TASC13 will highlight the first results emerging from the full-sky, double-hemisphere TESS data exploration, in synergy with other and complementary large-scale surveys. The TASC6/KASC13 workshop will take place from 11-15 July 2022 at KU Leuven, Belgium - one of the most active asteroseismic centres in Europe - and the scientific programme covers a broad range of research topics.

The Triennial Earth-Sun Summit is a joint meeting of the AAS Solar Physics Division and the Space Physics and Aeronomy Section of the American Geophysical Union.

TESS welcomes participation by the entire Heliophysics community, including all four traditional sub-disciplines devoted to studies of the Sun, Heliosphere, Magnetosphere, and Ionosphere-Thermosphere-Mesosphere. TESS not only promotes greater interaction and unity within Heliophysics, but also connections to astrophysics and planetary physics.
