This program is motivated by the recent observational insights concerning white dwarfs as individuals and as a population, based on the astrometry from Gaia and large photometric (Kepler, TESS, ZTF, VeraRubin) and spectroscopic (SDSS-V, DESI, WEAVE, 4MOST) surveys. Some of the questions that these data, combined with improved input physics and white dwarf models, will answer are: How does crystallization affect white dwarf cooling? How good is our understanding of convection, overshoot, and mixing in general? How good are the predictions of the low-frequency gravitational wave foreground and thermonuclear supernovae rates (SN Ia, Iax, Ca transients)? What is the nature of the recently discovered stellar remnants of thermonuclear supernova and/or their donors? What are the architectures of planetary systems that survive the metamorphosis of their host stars into white dwarfs, and what is their ultimate fate?

We are witnessing a profound rapid change in our understanding of the phenomenon of Gravitation. We are exploring various implications of the general theory of relativity, and of its modified versions, in which gravitation is a consequence of the curvature of spacetime and also various investigations into the mathematical foundations of the general theory of relativity, the nature of spacetime, and the imprints of quantum mechanics. We have been commissioning sophisticated high energy experiments aiming at understanding the elementary particles that are the fundamental constituents of baryonic and leptonic matter and their underlying forces.

The AdS/CFT Correspondence, an enduring cornerstone of theoretical physics, turns 25 in November 2022. An outstanding problem in AdS/CFT is to understand the origins of the correspondence in the most fundamental terms possible. Harnessing substantial progress over the last several years in nonperturbative quantum and conformal field theory, this program will develop a constructive approach to the emergence of bulk spacetime in AdS/CFT, rooted in the rigorous modern language of conformal field theory and the conformal bootstrap. By leveraging a new generation of techniques, the program aims to constrain gravitational observables and to sharpen our understanding of the principles governing the quantum gravity landscape. The program will extend the horizons of the conformal bootstrap itself, by applying existing techniques to new holographic observables and by drawing lessons from non-bootstrap approaches.

We organise a 3-week programme bringing together theoretical physicists and mathematicians working in the areas of gravity, dualities, extended geometry, field theory, higher homotopy structures, and other infinite-dimensional superalgebras. The overarching goal is to make progress in constructing “exotic” field theories, where conventional notions of spacetime break down, and thus traditional methods fail. These include exotic forms of gravity, extended (double and exceptional) geometry, string/M-theory and its dualities, and higher spin theories. The common feature of these theories is the appearance of higher symmetry algebras, generalising the notion of Lie algebras. In this programme, we will bring physicists and mathematicians together working on these “higher structures” in order to better understand the fundamental structures of physical theories and develop a bootstrap based on higher structures.

The last several years have seen rapid development of a new language for conformal field theory(CFT), including insights from the conformal bootstrap program. This conference will bring to bear the modern arsenal of conformal field theory on the foundations of holography and quantum gravity. A theme of the conference will be the extent to which consistency conditions on quantum gravity are inherited from those of CFT, and whether they naturally lead to string/M-theory. By bringing together scientists on both sides of holographic duality, we hope to explore these issues in a broad way.Topics to be covered include large N bootstrap and the structure of holographic CFTs dual to general relativity; CFT sum rules and gravitational effective field theory; aspects of supersymmetry in holography; low-dimensional holography, modularity and quantum chaos; black holes from strongly-coupled finite temperature physics; symmetry constraints on gravitational path integrals and AdS vacua; S-matrices, their relation to CFT correlators, and holography away from AdS.

The origin of cosmic magnetism is one of the most fascinating topics in astrophysics and cosmology. Both a primordial or an astrophysical origin are consistent with current observations, which include upper limits on primordial magnetic seeds from the cosmic microwave background (CMB), detection of magnetic fields in large scales structures, and lower limits on the magnetisation of voids inferred by TeV blazars observations (difficult to explain by fully astrophysical seed magnetic fields). This new (hybrid) conference comprises different technical and theoretical expertises in a unique way.

The cosmic web of the matter distribution in the universe provides the framework for the formation and evolution of galaxies and is fundamental to connect galactic properties to cosmology. This conference will address the effects of the cosmic web upon galaxies and vice versa. The aim is to create both a broad-brush and then, for some aspects, a more detailed, early to late time joint history of the web and galaxies. Indeed, the web reflects what the universe is on intermediate scales, which are informative, both in terms of cosmic evolution and quantity of data. It acts as a dynamically relevant intermediate-density bridge (easier to model) between cosmology and galaxies. It is also the source of all anisotropy, critical for angular momentum acquisition, which is the number two parameter in galaxy formation.

High-cadence long-term monitoring of the transient sky suggests that most core-collapse supernovae are influenced at some level by interaction with circumstellar material. Although considered so far a feature in core-collapse supernovae, this observation has led theorists to revise the idealized view of massive star evolution and explosion, introducing a slew of time-dependent, dynamical, and multi-dimensional effects that remain today poorly understood. Bringing together experts on this multi-faceted domain of astrophysics, this MIAPP programme will allow the community 1) to investigate the various mechanisms at the origin of eruptions and explosions of massive stars, 2) to improve the techniques of radiation hydrodynamics and radiative transfer modeling of these events, 3) to integrate these advances in order to dissect the rapidly growing observational zoo of interacting supernovae, and 4) to quantify the influence of circumstellar interaction on supernova-based extragalactic distance measurements. This gathering will prepare the supernova community for the upcoming era of transient astrophysics with the Vera Rubin Observatory LSST.

“Time” and “clock” are ubiquitous notions that every physicist is working with, irrespectively of whether that work is experimental or theoretical in nature. In spite of that, the theoretical meanings as well as the operational realisations of these concepts are far from obvious and certainly not unique. A whole spectrum of shifts in, and losses of, interpretations occur in the transitions between classical mechanics, quantum mechanics, special-relativistic quantum-field theory, general relativity, and, finally, quantum gravity. As a result of this, issues arise that, up to this day, are the subject of challenging and often controversial debates. Recent developments in high-precision metrology partly help to resharpen but partly also refuel these controversies. Our seminar intends to bring together scientists from different disciplines in order to foster a productive dialogue on the problematic issues in connection with “time” and “clock”. We specifically aim to characterise, in scientific terms, a common understanding of what the “problem of time” really entails. Our seminar addresses Ph.D. students as well as researchers beyond their Ph.D. degree.

"Neutrino physics is largely the art of learning a great deal by observing nothing." This quote attributed to Israeli physicist Haim Harari, while not doing justice to modern neutrino detectors for which event pile-up is an actual issue, nevertheless illustrates the fascination exuded by the lightest of all (known) fermions. The goal of the CERN Neutrino Platform Pheno Week 2023 is to bring together those who share this fascination around the world. The focus of the workshop will be primarily on phenomenology and theory

The meeting will take place in person in Ponte de Lima, which is the oldest municipality in Portugal (chartered in 1125) and about 90min away from Porto airport by express bus. The meetings are informal, and there is no registration fee. There will be no invited speakers, parallel sessions, or posters, and all the time slots will be of equal length. Should there be excessive abstract demand, some preference will be given to younger participants. The meetings are not restricted to a single focused topic, but are open to cosmologists in the broadest sense, from theoretical particle physics to observational astrophysics. Stimulating interactions between theorists and observers is a particular concern of the organizers, and will be the key factor for the success of the meeting. In addition to the talks, there may also be time for guided discussions, particularly if there are several requests for talks on a common hot topic. The meeting will also include a programme of social and educational/outreach activities.

The primary goal of the meeting is to discuss complementary aspects of elementary particle phenomenology both within the standard model and beyond: those relevant for the third and high luminosity runs of the Large Hadron Collider and possible future high energy colliders; in high intensity experiments measuring neutrino oscillations, quark/lepton number, flavour and CP violation; in astroparticle observatories probing the matter-energy content of the early and present universe. Planned topics to be covered include Higgs boson and electroweak physics, top quark physics, flavour phenomena and CP violation, neutrino physics, dark matter as well as other particle dynamics in the early universe.

Soon after Einstein postulated the General Theory of Relativity, he introduced what he called his "greatest mistake'', the so-called cosmological constant. Solutions of the Einstein equation with cosmological constant are now called Einstein manifolds, and despite Einstein's pessimistic view, play key roles both in mathematics and physics. Quasi-Einstein manifolds are generalizations of Einstein manifolds, which include not only Einstein manifolds but Ricci solitons, warped product Einstein manifolds, static Einstein manifolds, and other special manifolds. These are important in many areas of modern mathematical research, including Ricci flow, collapsed Gromov-Hausdorff limits, and general relativity. This workshop will examine progress in seemingly disparate fields which in fact share a common nexus, namely quasi-Einstein manifolds or the related notion of Bakry-Emery Ricci curvature. Problems to be discussed include the classification problem for near horizon geometries (of black holes), for Ricci solitons and for static Einstein metrics, as well as the fundamental gap problem for Laplace and Schroedinger operators, and the formulation and application of synthetic Bakry-Emery Ricci curvature.

The purpose of this workshop is to bring together scientists with different backgrounds and expertise to discuss open problems, recent developments and future directions in axion physics, a field that is notoriously replete with interdisciplinary connections. The aim is to foster a fruitful cross breeding between different theoretical areas, with a focus on certain open issues in axion particle physics, astrophysics and cosmology. Quantitative assessments of the axion contribution to Cold Dark Matter (CDM) involve top-notch lattice simulations of non- perturbative QCD effects, as well as of the cosmic evolution of axionic topological defects. Astrophysical observations provide strong bounds on axion properties because stellar evolution would be affected by the existence of axions and, intriguingly, some excesses in star energy losses have been reported. Cosmological scenarios in which the PQ symmetry is broken before inflation foresee axions imprints in the CMB, while in post-inflationary scenarios axion miniclusters, with overdensities several orders of magnitude larger than the local density of CDM, are expected to form, and a reliable assessment of their properties is of utmost importance. From the experimental side, a blossoming of potentially game-changing ideas, with an exciting crossover from experimental particle physics to materials science and cutting-edge technologies is inspiring new methods for axion searches. Novel techniques have been put forth that, besides exploiting the axion- photon coupling, aim to reveal axions via their couplings to nucleons and electrons. The interaction between the experimental and theoretical communities will foster the merging of `how to search’ with `where to search’ into optimized strategies to hunt for the axion.

The aim of this meeting is to bring together researchers from astronomy, gas-phase, solid state and surface physics, and chemistry communities to address the wide-ranging roles of chemistry in astronomy in the light of the wealth of observational detail becoming available in this era of high resolution astrochemistry. Our window on the universe is being opened more widely as new observational platforms are developed that will overcome the limitations of resources currently available to astronomers. Together we will address the role of chemical spectroscopy in identifying chemical species and probing their environments; we will attempt to understand the interplay of gas-phase, surface, solid state and photochemically-induced processes that drive the chemical evolution of our Galaxy and others; how this chemical evolution is intimately involved in controlling the process of star and planet formation; and how chemistry brings us to the edge of biology.

This workshop will be co-organized by two main institutions, namely the University of Naples Federico II and the University of Durham.

This workshop aims to discuss the phenomenological implications of Primordial Black Holes (PBH), such as their possible relationship with dark matter origin, neutrino mass, the baryon asymmetry, inflation, their theoretical aspects and origin and the possible multi-messenger detection and the experimental state-of-the-art. Recently, the interest in PBHs from the physics community is growing because they can provide an alternative explanation of some of the major problems of the Standard Model. We know that Black Holes can merge or evaporate (according to the seminal paper by Hawking), generating gravitational waves, fluxes of Dark Matter, and standard model particles. Therefore, different experimental indirect searches can possible exploit the multi-messenger approach.

Over the past decade, the astronomical community has invested enormous efforts to exploit major ground- and space-based facilities. The advent of stellar spectroscopic surveys, such as Gaia-ESO, GALAH, and APOGEE, paved the way for the large-scale analysis of the chemical compositions of millions of stars. Time-domain photometry missions, such as CoRoT, Kepler, and TESS, allowed detailed characterization of the interior structure of stars by asteroseismic techniques. Interferometric observations with VLTI and CHARA provide new information about stellar diameters and the circumstellar environment. With Gaia, stellar luminosities and radii of millions of stars can now be derived. The upcoming facilities and surveys, such as SDSS-V, 4MOST, PLATO, LSST, and JWST will revolutionize the field with unique time-domain information, and an increase in sample size by orders of magnitude. The main challenge is to combine the large amount of high-quality observations into a general coherent picture of the fundamental parameters of stars and to position them within the context of theoretical stellar structure and stellar evolution. The MIAPP program will assess the state-of-the-art in the field and develop concepts for new strategies and models to move towards the percent-level precision and accuracy in diagnostics of stellar structure.

This MIAPP program will focus on theoretical and observational challenges in the broad area of Stellar Astrophysics.

Defining a theory of quantum gravity remains one of the most challenging problems at the cutting edge of research in mathematical and theoretical physics. Unlocking this problem implies constructing a quantum field theoretic description of gravity which fully elucidates how a quantum field theory encodes gravitational spacetime background solutions. Much of the progress in shaping the language and the framework of this problem owes its genesis to a specific subset of problems in quantum gravity, namely those dealing with understanding the organisation of information in black holes.

This workshop aims to bring together researchers from number theory, automorphic representation theory and string theory to explore how automorphic forms that encode degeneracies of BPS could be related to and feed into information theoretic concepts such as quantum error corrections, applied to BPS and near-extremal black hole backgrounds, and to develop machine learning techniques to unveil some of the hitherto undefined automorphic structures underlying the generating functions for BPS black hole microstates in superstring models. This event is the first workshop of the 4-month long BLH programme at the INI centred around the same topics.

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 2023 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.

While it is widely acknowledged that string theory provides a framework for addressing quantum gravitational (and even quantum field theoretic) questions, the precise nature of its organizational principle remains obscure. Nearly three decades ago, when the question “What is string theory?” was asked, the perturbative string worldsheet viewpoint played the starring role. Since then, the discovery of D-branes, string dualities, and the holographic AdS/CFT correspondence has had spacetime dynamics taking center-stage. Much insight has been gleaned from these developments. We now have, for example, a much broader class of string backgrounds with better control over compactifications; strong constraints on the low energy effective field theories; a plethora of gauge-string dualities as well as applications of holographic techniques to a wide class of physical problems; and new angles on semiclassical gravitational physics from a fruitful interplay with quantum information in holography. Together with an influx of new tools and techniques, we have a very rich set of perspectives that illuminate the subject we continue to call string theory. While all these developments are interesting in and of themselves, it is an opportune moment to attempt to synthesize these, often disparate, strands and arrive at a deeper answer to the question in the title.

Turbulence is an important process in various astrophysical environments and over vast scales. These environments range from the interior of stars, the solar wind, accretion flows, disks, jets, the interstellar medium and the circumgalactic medium, to the intra-cluster medium. The past few decades have seen great advances in both observational and theoretical studies of astrophysical turbulence. The advances in understanding and measuring turbulence have also brought significant changes to many branches of astronomy.

This conference will bring together turbulence experts from a wide range of subfields in astrophysics and physics. The goal is to encourage and enhance interdisciplinary discussions and collaborations. The conference will cover many topics, including: turbulent dynamo, magnetic reconnection, plasma physics, space physics, unresolved physics and sub-grid models in numerical simulations, turbulence in the laboratory, new observational techniques for diagnosing turbulence, connecting observations and models, and astrophysical applications of magnetized turbulence (e.g. star formation, cosmic rays, accretion, galaxy formation and evolution).

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.

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.

Tidal disruption events (TDEs), which occur when a star is destroyed by the immense tidal field of a supermassive black hole, fuel luminous accretion flares that provide unique insight into the properties of galactic nuclei and their central black holes. The detection rate of these events has accelerated in recent years thanks to advances in wide-field survey capabilities across the electromagnetic spectrum. Nonetheless, there remain theoretical uncertainties in the modeling of TDEs that obfuscate understanding in the face of observations, and our ability to use TDEs as a collective Rosetta Stone for deciphering black hole demographics across cosmic time remains elusive. To bridge theory and observation and to start to tap the wealth of understanding contained within TDE observations, this conference aims to unite the diverse field of astronomers working on TDEs and the related fields of variable Active Galactic Nuclei (AGN) and X-ray binaries. This conference will highlight the recent advances that have been made in understanding TDEs, make connections to related astrophysical phenomena, and elucidate the most outstanding questions in TDE theory and observation.

The international conference Loops ‘24 is the most recent in a long tradition of biennial meetings focused on loop quantum gravity and background independent approaches to quantum gravity. The conference will be held from Monday, May 6 through Friday, May 10, 2024, at the campus of Florida Atlantic University in Fort Lauderdale, Florida (USA). The program will feature morning plenary talks complemented by contributed talks. Plenary sessions will be held in the auditorium of the Broward County Main Library one block away from the campus. The conference will highlight recent developments in canonical loop quantum gravity, covariant loop quantum gravity (spin foams), and other approaches to quantum gravity, as well as applications to symmetry-reduced models, quantum cosmology, black holes in quantum gravity, and other topics. Foundational, mathematical, numerical and phenomenological aspects will be covered.

Observables spanning a wide range of cosmic epochs and length-scales independently testify to the existence of dark matter. Although little is known about the microphysical nature of dark matter, its mere existence points to physics beyond the Standard Model. New developments in theory, cosmological simulations, and observational capabilities in the era of large surveys have opened up a vast landscape for dark matter discovery, which includes models that can only be tested by astrophysical and cosmological probes.

COSMO'24 will take place for October 21-25, 2024 in Kyoto, Japan. It will bring together a wide range of cosmologists and particle physicists to discuss current ideas on particle physics and cosmology.

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.
