Quasinormal Signatures of Quantum Gravity at Horizons

ORAL  · Invited

Abstract

One of the central goals of quantum gravity is to uncover the microscopic origin of the thermodynamic laws obeyed by black hole and cosmological horizons. Quantum corrections sharpen these laws and provide stringent constraints on candidate microscopic models. I will explain how the leading corrections are largely encoded in the quasinormal spectrum of the spacetime. I will also comment on additional contributions from edge modes, degrees of freedom that reside on the horizon.
