Energy scales and black hole pseudospectra: the structural role of the scalar product
Edgar Gasperin, José Luis Jaramillo
A pseudospectrum analysis has recently provided evidence of a potential generic instability of black hole (BH) quasinormal mode (QNM) overtones under high-frequency perturbations.…
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…
