The first joint gravitational wave and electromagnetic detection of the binary neutron star GW170817 marked the dawn of the multi-messenger era with GWs. This watershed event opened a new window to study phenomena such as heavy element nucleosynthesis, black hole formation, the Universe's expansion rate, the equation of state of dense matter, and the intricate dynamics of relativistic jets. These profound inquiries have reignited interest in investigating similar physical processes at play in black hole-neutron star mergers and core-collapse supernovae. This endeavor necessitates the development of predictive models in anticipation of forthcoming observations in 2024 by LIGO-Virgo-KAGRA, Rubin Observatory, and future observation campaigns, that will transform the field of high-energy astrophysics transients. The primary goal of this workshop is to bring together physicists with diverse backgrounds in both theoretical and observational expertise within the domains of electromagnetic, gravitational wave, and particle emissions. Collectively, they will engage in collaborative efforts to identify and investigate pathways for tackling the pivotal scientific questions at the core of this rapidly evolving field.

Time-domain astronomy is rapidly evolving, and astronomers have become increasingly good at catching fast transients on very short timescales. Additionally, both theorists and observers working on astrophysical transients have a habit of expanding their science across several subfields, resulting in a highly interconnected community. This motivates a continuous opening of new lines of communication between transient scientists, developed in a highly active and engaging conference setting. Rise_Time is a conference for transient astrophysicists of all kinds; theorists, observers, and numericists; experts on gravitational waves, radio, optical, IR, UV, X-Rays, gamma rays, cosmic rays, neturinos, and any other observing technologies we didn't think to mention. We aim to generate a highly diverse, inclusive, and interactive environment, with plenty of time and energy allocated for questions and interactive discussions. Attendees are encouraged to be participants rather than spectators.

The exploration of cosmic dawn is currently in an exceptionally exciting phase, and we expect the immediate future to be even more exciting with a new set of discoveries delivered by JWST. The observations of first stars, galaxies, and black holes with JWST and other facilities provide a unique “stress test” for a new generation of theoretical models of galaxy formation. The aim of the conference is to bring together theorists and observers to discuss the following key questions: What can we learn from JWST data on the nature of the first stars and black hole seeds? What is the nature of the stellar populations inhabiting the first galaxies? What are the star formation and chemical enrichment histories of early galaxies? Do we understand the key physical processes that shape the evolution of these early galaxies and their black holes? How can we connect the pictures derived from near-field and deep field observations?

Over the past ten years tremendous progress has been achieved in quantum field theory thanks to the realization that symmetries can be interpreted in terms of the action of topological defects on the space of operators. This gives a generalization of the notion of symmetries, explicitly realized in many instances exploiting Lagrangian field theory techniques, uncovering a rich and unexpected landscape of physical effects in condensed matter, high energy physics, and quantum gravity. This conference will bring together the major experts in the subject, and strives to be an opportunity for participants to quickly get up to speed with the most recent advances and open problems in the field.

The Kepler and TESS missions, as well as ground-based telescopes, have discovered thousands of planets on short-period orbits around other stars, including many that are Earth-size and likely to be rocky. These objects have no direct counterparts in the Solar System, and the corresponding inner regions within the protoplanetary disks that spawned them are challenging to study. This conference will confront this challenge and advance our understanding of the nature, formation and evolution of Earth-sized planets in inner protoplanetary disks by bringing together diverse experts in exoplanet demographics, protoplanetary disks, models of disks and planet formation, and meteoritics to address four key questions: (1) what is the nature of close-in rocky planets and their atmospheres? (2) do they form in situ or migrate inwards after forming further out? (3) what are the governing parameters that could vary between star systems? and (4) why are there no analogous planets around the Sun? The conference will complement and energize the associated KITP Program by including a broader range of participants and highlighting recent observational results. The goals of the conference are to synthesize current knowledge of the properties of planets and inner disks, describe the state of the art in models of planet formation and evolution, catalyze interactions between different fields, and chart a path forward for advances in observations, theory, and computational modeling.

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.
