Since 1963, the Texas Symposium on Relativistic Astrophysics has been one of the most important international conferences in astronomy and physics. Traditionally, it moves around the globe and takes place in different cities every two years.

The 33rd Texas Symposium on Relativistic Astrophysics will take place in the vibrant city of Tempe, AZ from December 8 – 12, 2025. The event will be hosted at The Omni Hotel very near Arizona State University which offers state-of-the-art facilities to ensure a productive and enjoyable meeting.

We are thrilled to announce that John Mather, Jim Peebles, Adam Riess, George Smoot (TBC), and Frank Wilczek have already agreed to participate and attend the symposium.

Beyond the symposium, Tempe in December offers a perfect blend of outdoor adventures and festive activities, making it an ideal winter getaway. The mild temperatures invite visitors to explore the scenic beauty of Tempe Town Lake, hike the iconic Hayden Butte, or stroll through the Desert Botanical Garden. You can also experience the Tempe Fantasy of Lights Boat Parade, a dazzling display of holiday lights along the lake. The city hosts various seasonal events, including holiday markets, outdoor concerts, and ice skating rinks, offering attendees a chance to enjoy the warm desert climate while celebrating the holiday season.

The symposium will cover all major topics on high-energy and particle astrophysics, cosmology and relativity. It will include morning plenary sessions and afternoon parallel sessions which will function as mini-symposia in each sub-field. The plenary sessions will consist of ~45 min review talks. The afternoon sessions will feature oral talks (about 15-30 min) and poster contributions.

We look forward to welcoming hundreds of international astronomers and physicists to Arizona in December 2025!

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 aim of the workshop is to explore the implications and next steps of recent advances in understanding the dynamics and thermodynamics of near extremal black holes. By bringing together researchers in this area spanning the wide range of approaches, from rigorous mathematics, perturbation theory, and numerical methods, the workshop will focus on future directions. Extremal black holes are mathematical solutions of Einstein's equations describing stationary black holes with either maximal spin or maximal charge, and these black holes have special properties such as zero temperature. Recent studies have found certain surprising aspects of their dynamics including scalar hair and an avenue for their formation from subextremal configurations that violate the third law of black hole thermodynamics. These results raise a number of questions including the stability and critical behavior of such solutions that may be addressed via other research avenues.

The Sachdev-Ye-Kitaev (SYK) model has proved to be a fertile ground for many areas of modern physics such as black holes, holography, condensed matter physics and many-body quantum chaos. In recent years, considerable progress has been made on the double-scaled limit of the SYK model (DSSYK), which is generic to a large class of p-local systems and beyond, and can be solved with great precision using combinatorial tools. New frontiers that emerged include noncommutative spacetimes and quantum groups, new “fake geometries” and negative distances in the bulk, and suggestions for the quantum nature of de Sitter gravity. All of the above topics are under active research by leading experts from different physics communities. We bring them together by for a one-week workshop at the SCGP to pursue further advancement in these research fields.

The Astrobiology Science Conference (AbSciCon) brings the astrobiology community together every two years to share research, collaborate, and plan for the future. AbSciCon is a community-organized conference that provides a forum for reporting on new discoveries, sharing data and insights, advancing collaborative efforts and initiating new ones, planning new projects, and educating the next generation of astrobiologists.

Supergravity is intrinsically associated with Stony Brook. It may well be the most significant physics discovery in the entire history of the Yang Institute. Since 1976, many researchers have worked to generalize the basic theory we found and apply it to the physics of elementary particles and gravity. Along the way supergravity has made contact with frontline mathematics, notably geometry and topology. The records of the Inspire archive vouchsafe for the fact that supergravity has become a major subject in theoretical physics. There are 6242 papers in which the word supergravity appears in the title and 19868 additional papers in which it is a keyword. (Keywords primarily appear in the abstract.) The subjects of these specialized lectures will be determined by the international committee. We also intend to cover the relation of supergravity to string theory (Maldacena, Schwarz), mathematics (Vafa), black holes (Warner) phenomenology (including cosmology) (Kallosh, Skenderis), and condensed matter (Erdmenger). We plan to have a panel discussion on the impact and future of supergravity.
