Black-hole spectroscopy: quasinormal modes, ringdown stability and the pseudospectrum

, 2023
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 gravitational waveforms could soon lead to high-precision gravitational-wave ...
