XVIII Black Holes Workshop, December 18-19 2025 in Lisbon

The eighteenth edition of the Black Holes Workshop will be held at the Instituto Superior Técnico, Lisbon, in December 18 and 19, 2025.  The venue will be on campus, at the Anfiteatro Abreu Faro.

About the Workshop

From astrophysics to high-energy physics, from information theory to quantum gravity, black holes have acquired an ever increasing role in fundamental physics, and are now part of the terminology of many important branches of observational, theoretical and mathematical physics.

The Black Holes Workshops gather researchers working on physical and mathematical aspects of black holes, using both classical and quantum approaches, within the frameworks of general relativity, semiclassical and quantum gravity, cosmology, and astrophysics, with the goal of stimulating interaction between these different fields.

The eighteenth edition of the Black Holes Workshop will celebrate the 10 years of the first gravitational-wave detection by the LIGO detectors.

Important dates:

  • Registration opens: September 15, 2025
  • Registration closes: December 5, 2025
  • Abstract submission deadline: November 21, 2025
