Testing GR with GWs

by Vitor Cardoso


One of the most remarkable possibilities of General Relativity concerns gravitational collapse to black holes, leaving behind a geometry with light rings, ergoregions and horizons. These peculiarities are responsible for uniqueness properties and energy extraction mechanisms that turn black holes into ideal laboratories of strong gravity, of particle physics (yes!) and of possible quantum-gravity effects.
I will discuss some of the latest progress in testing the black-hole nature of compact objects, and of using black holes as particle detectors.
