2nd New Horizons for Psi Workshop – Black Holes and Fundamental Fields, August 24-28- 2026 in Beijing The New Horizons for Psi Workshop is an international conference series devoted to exploring fundamental fields in the vicinity of compact objects, and to understanding how these extreme gravitational environments can serve as powerful laboratories for fundamental physics. The growing interplay between black hole astrophysics, gravitational-wave observations, and particle physics has opened new opportunities to probe phenomena at the intersection of these fields. The workshop brings together researchers working on black holes, gravitational waves, and particle physics, fostering cross-disciplinary dialogue. Workshop Website

AG splinter session on Relativistic Astrophysics, September 11 2026, Garching, Germany This session covers the observational and theoretical aspects of the physics in strong gravitational fields and of the emergence of high energy phenomena. Strong gravity and relativity will be important for the formation and nature of white dwarfs, Neutron Stars and Black Holes. Physical phenomena in the vicinity of compact objects are lensing and shadows, the motion of stars in strong gravitational fields, gravitational waves, accretion disks, jets, and Gamma-Ray-Bursts. Also the aspects of relativity in cosmology and dark matter search will be part of this session. Session Website
