Black Hole Tomography: Unveiling Black Hole Ringdown via Gravitational Wave Observations
A. Ribes Metidieri, B. Bonga, B. Krishnan
During the post-merger regime of a binary black hole merger, the gravitational wave signal consists of a superposition of quasi-normal modes (QNMs) of the remnant black hole. It ha…

Nonlinear ringdown at the black hole horizon
Neev Khera, Ariadna Ribes Metidieri, Béatrice Bonga +6
The gravitational waves emitted by a perturbed black hole ringing down are well described by damped sinusoids, whose frequencies are those of quasinormal modes. Typically, first-or…
