Quantum Black Holes in the Sky?

The past decade has witnessed significant breakthroughs in understanding the quantum nature of black holes, with insights coming from quantum information theory, numerical relativity, and string theory.  At the same time, astrophysical and gravitational wave observations can now provide an unprecedented window into the phenomenology of black hole horizons.  This workshop seeks to bring together leading experts in these fields to explore new theoretical and observational opportunities and synergies that could improve our physical understanding of quantum black holes.
