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

Researchers working on black holes in all their aspects are kindly invited to participate. A limited number of contributed talks will be selected based on scientific merit. Late submissions will not be considered. Please refer to the registration instructions for further details.

Workshop Website

The workshop will cover a broad range of issues in gravity and theoretical aspects of cosmology. Some concrete examples of relevant topics are gravitational instabilities and collapse problems, singularity resolution, canonical approaches to gravity quantization and quantum cosmology, statistics of fluctuations in cosmological spacetimes, primordial black holes, cosmological dynamics of fundamental constants, etc. The talks are expected to be informal and interactive, with a substantial pedagogical component. We strongly encourage blackboard presentations.

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.

Gravitational-wave astronomy is rapidly advancing, driven by expanding observational datasets from LIGO-Virgo-KAGRA and pulsar timing arrays. Harnessing these increasingly complex data for astrophysical discovery requires accurate modeling of signals and noise, efficient detection methods, and scalable Bayesian inference techniques.

Artificial intelligence (AI)—including simulation-based inference and advanced architectures like transformers and diffusion models—is reshaping data analysis across science, including gravitational waves. AI-driven techniques already enhance detection sensitivity, accelerate parameter estimation, and mitigate non-Gaussian detector noise. Yet next-generation observatories such as LISA, the Einstein Telescope, and Cosmic Explorer, will present unprecedented challenges: millions of detectable sources, overlapping signals, and more complex astrophysical signals. Fast, reliable inference will be crucial for timely multi-messenger follow-up and continued scientific breakthroughs.

This workshop brings together experts from gravitational-wave astronomy, artificial intelligence, and astrophysical modeling to define key challenges and opportunities for AI in the coming decade. Through interdisciplinary discussions, participants will define pathways to enhance detection and parameter estimation, waveform modeling, and population analysis. The goal is to develop a strategic roadmap for integrating AI methods into gravitational-wave science and maximize the return from future observational campaigns.

The workshop is organized by Max Dax, Davide Gerosa, Stephen Green, and Natalia Korsakova at the Sexten Center for Astrophysics, which is located in the beautiful Dolomites, in the Italian Alps. Sexten overlooks the Tre Cime di Lavaredo (Three Peaks of Lavaredo) which are among the most iconic peaks in alpinism history. Scientific sessions are hosted at Haus Sexten, right next to the ski slopes.
