Gravitational radiation from hyperbolic orbits: a self-force perspective
By Niels Warburton
Naturalness of black-hole tides
Appears in collection : Balzan Conference on Open Issues in Gravitation
In this talk I will explain how certain aspects of black-hole physics can be understood using ideas from effective field theory. Many of the familiar notions from particle physics will play a role, including the renormalization group, universality and naturalness. In particular, I will explain why black holes naively seem like fine-tuned systems, but they are ultimately not thanks to an accidental symmetry of General Relativity. The talk is based on work in collaboration with Alessandro Podo.
