An overview of quasinormal modes in modified and extended gravity
Flora Moulin, Aurélien Barrau, Killian Martineau
As gravitational waves are now being nearly routinely measured with interferometers, the question of using them to probe new physics becomes increasingly legitimate. In this articl…
Analytical proof of the isospectrality of quasinormal modes for Schwarzschild-de Sitter and Schwarzschild-Anti de Sitter spacetimes
Flora Moulin, Aurélien Barrau
The deep reason why the equations describing axial and polar perturbations of Schwarzschild black holes have the same spectrum is far from trivial. In this article, we revisit the…
Quasinormal modes of black holes in a toy-model for cumulative quantum gravity
Aurélien Barrau, Killian Martineau, Jeremy Martinon +1
The idea that quantum gravity effects might leak outside the horizon of a black hole has recently been intensively considered. In this study, we calculate the quasinormal modes as…
