This conference aims to explore the application of data-driven tools to learn about galaxy formation physics. It endeavors to maximize the gain from astrostatistics, data science, and machine learning for the galaxy formation field as a whole, by emphasizing the translation of data-driven results to physical understanding. This conference will focus on a sharing of expertise in data exploration and analysis tools, and an open discussion of how these may teach us about the physics of galaxy formation and evolution.

Green bank Observatory

This 3-day workshop at the Green Bank Observatory will focus on topics related to the role of oxygen in the universe, planets and life, and how the rise of oxygen on Earth may (or may not) likely have analogs on other planets. Attendance is limited to 50 participants, by application only, and all registration and travel expenses will be covered. The conference scope should be construed broadly; researchers working on any related problems are strongly encouraged to apply. Recognizing the challenges the pandemic has presented for networking over the past several years, this workshop will have a strong focus on early career researchers, and will have broad international participation. Presenters are encouraged to gear their talks to an interdisciplinary audience, eschewing the trees of internecine disciplinary debates for the forest of broader understanding.

Gauged linear sigma models (GLSMs) have provided key insights into numerous aspects of string theory and supersymmetric field theory and have been a bridge to various fields in mathematics such as enumerative and algebraic geometry and category theory. The aim of this workshop is to bring together experts from mathematics and physics to celebrate 30 years of GLSMs by addressing topical research questions and identifying new applications. Topics include: GLSMs in the context of mirror symmetry, new types of stringy (Calabi-Yau) geometries, homological projective duality and generalisations thereof, SUSY gauge theories in more than two dimensions, generalized cohomology, quantum K-theory, and mathematical invariants stemming from a rigorous mathematical definition of GLSMs.

Royal Society of Chemistry

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.

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.

University of Michigan

We are pleased to announce the second Michigan Cosmology Summer School from June 5-9, 2023 at the University of Michigan campus in Ann Arbor, MI. The target participants are graduate students and junior postdocs. Additional details are in the Summer School website: https://johannesulf.github.io/cosmology-school-2023/, including a preliminary list of lecturers. While we expect the majority of participants to be in-person, we will provide a hybrid setup, opening lectures and interaction spaces to online participants. This should significantly broaden the accessibility of the School to junior scientists based in countries from which it is expensive and difficult to travel to the U.S. The school will cover topics across the field of cosmology ranging from theory to experiment, but the emphasis will be on computation and the interface between data and theory. An overarching goal of the school will be to provide participants with concrete practical skills for data modeling. The focus will be on the theoretical underpinnings of inflation, dark matter, and dark energy using modern measurements, principally those coming from the LSS and CMB. The registration opens late January. The Leinweber Center for Theoretical Physics will heavily subsidize registration costs to minimize barriers for attendees. The weather in Michigan that time of the year should be very nice, with long sunny days. We are planning to organize some outdoor activities as well.

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.

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.

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.
