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

8th Black Hole Nepal Meeting, October 12-16 2026 in Kathmandu The 8th BH Nepal meeting: Many Faces of Stellar-Mass Black Holes, which will take place in Kathmandu, Nepal, on 12-16 October 2026. The aim of the conference is to bring together theorists and observers to discuss recent progress in the study of stellar-mass black holes, their formation and evolution, and their observational signatures across the electromagnetic spectrum and beyond.
