10th Physics and Astrophysics at the eXtreme Workshop and 3rd Cosmic Explorer Symposium
The 10th Physics and Astrophysics at the eXtreme (PAX) Workshop and the 3rd Cosmic Explorer Symposium are events sponsored by the Physics Department of the University of Illinois at Urbana-Champaign and taking place in Urbana, Illinois on June 30 – July 3, 2025 at the Beckman Institute Auditorium (Room 1025) and Room 1005.
The meeting aims to explore how gravitational and electromagnetic wave observations can help us understand extreme physics, including strong gravitational fields, dark matter, nuclear physics, cosmology, and multimessenger astrophysics. The Cosmic Explorer Symposium will bring together the community to discuss important aspects of the design and operations of the Cosmic Explorer gravitational-wave observatories, covering both observational and instrument science. Together, PAX-X and the Cosmic Explorer Symposium will explore the science opportunities that come with the next-generation gravitational-wave detectors.
