Black hole ringdown

WebApr 12, 2024 · Black hole echo is an important observable that can help us better understand gravitational theories. The non-linear electrodynamic black holes can admit multi-horizon, and the destruction of outer horizons does not violate the weak cosmic censorship, which leads to the multi-peak effective potential for the scalar perturbations … WebJan 2, 2024 · Each black hole model predicts differences in the gravitational waves emitted during the ringdown phase, which stem from differences in the black hole's interior structure. With different...
