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

BIFROST – Black hole Insights: navigating the FROntiers of SpaceTime, October 20-22, 2025, Odense

In Norse mythology...the Bifröst is a blazing rainbow bridge that connects Midgård (Earth) and Asgård, the realm of the gods.

In a similar spirit, black holes represent bridges between classical gravity and the uncharted territory of quantum gravity.  General relativity well describes the spacetime surrounding black holes, yet understanding their interiors requires quantum gravity.
"Bifrost: Black Hole Insights – navigating the FROntiers of SpaceTime" is a dedicated workshop aimed at gathering leading experts from observational astronomy to theoretical physics. Together, participants will explore novel ideas that will help bridge classical and quantum gravity.

The workshop is jointly organized by organized by the Quantum Field Theory Center (QTC) at the Danish Institute for Advanced Studies, the University of Southern Denmark (SDU), Helsinki University and the Department of Physics “Ettore Pancini” of Federico II University.  

The event will take place on QTC premises at the Danish Institute for Advanced Study, in Odense, Denmark.

You can submit an abstract for a contributed talk in the registration form. The deadline for both registration and abstract submission is the 10th of September.
