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

XV International Conference on New Frontiers in Physics (ICNFP2026), August 19-30 2026, Crete, Greece The International Conference on New Frontiers in Physics aims to promote scientific exchange and the development of novel ideas in science, with a particular emphasis on interdisciplinary collaboration. The conference will bring together experts from around the world, as well as promising young scientists working on experimental and theoretical aspects of particle, nuclear, heavy ion, and astroparticle physics and cosmology, along with colleagues from other disciplines, such as solid-state physics, mathematics, mathematical physics, quantum optics, and more.

Ripples Through Time: Past Triumphs, Mapping the Future, November 25-27, 2026 at UWA Perth Celebrating 50 years of gravitational wave research, science education, and future innovation A century ago gravitational wave detection was thought to be impossible. Fifty years ago it was the quest of a small bunch of intrepid physicists. They faced challenge after challenge, but their optimism persisted. They uncovered new physics, invented novel instruments and new techniques. New disciplines like quantum optomechanics, space laser communication, clock technology and airborne exploration technologies emerged from their efforts. Year after year they overcame setbacks, never imagining that it would take 40 years of struggle to achieve their quest. Symposium Website

Ringdown in Lisbon, October 19-21, 2026 In the last year, the realm of black hole quasi-normal modes have been more vibrant than ever. The large number of updates is recognisable in the rise of a vibrant, young and motivated community that is pushing the boundaries of where we can test the nature of black holes with gravitational waves observations. The aim of this workshop is to give a space to this community for relaxed discussion session and fostering the birth of collaborations. Workshop Website
