Destabilizing the Fundamental Mode of Black Holes: The Elephant and the Flea
Mark Ho-Yeuk Cheung, Kyriakos Destounis, Rodrigo Panosso Macedo +2
Recent work applying the notion of pseudospectrum to gravitational physics showed that the quasinormal mode spectrum of black holes is unstable, with the possible exception of the…
Black holes in galaxies: environmental impact on gravitational-wave generation and propagation
Vitor Cardoso, Kyriakos Destounis, Francisco Duque +2
We introduce a family of solutions of Einstein's gravity minimally coupled to an anisotropic fluid, describing asymptotically flat black holes with "hair" and a regular horizon. Th…
Pseudospectrum of Reissner-Nordström black holes: quasinormal mode instability and universality
Kyriakos Destounis, Rodrigo Panosso Macedo, Emanuele Berti +2
Black hole spectroscopy is a powerful tool to probe the Kerr nature of astrophysical compact objects and their environment. The observation of multiple ringdown modes in gravitatio…
Gravitational wave signatures of black hole quasi-normal mode instability
José Luis Jaramillo, Rodrigo Panosso Macedo, Lamis Al Sheikh
Black hole (BH) spectroscopy has emerged as a powerful approach to extract spacetime information from gravitational wave (GW) observed signals. Yet, quasinormal mode (QNM) spectral…
