Schrödinger perturbation theory for black hole quasinormal modes
Jacopo Lestingi, Laura Sberna, Stephen R. Green
Deviations from vacuum general relativity (such as modified theories or the presence of an environment) produce small shifts in black hole quasinormal mode (QNM) spectra. These eff…
Kahler decoupling for Kerr perturbations
Stephen R. Green, Kirill Krasnov, Adam Shaw
The Euclidean Kerr metric is conformal, in two distinct ways, to a Kahler metric, with conformal factors determined by the repeated eigenvalue of the two chiral halves of the Weyl…
Excitation of scalar quasi-normal modes from boson clouds
Enrico Cannizzaro, Marco Palleschi, Laura Sberna +2
Massive scalar fields on black hole backgrounds generally admit two families of modes: quasi-bound states (QBS) and quasinormal modes (QNM). We demonstrate the orthogonality betwee…
Black hole spectroscopy: from theory to experiment
Emanuele Berti, Vitor Cardoso, Gregorio Carullo +65
The "ringdown" radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of black hole quasinormal modes a…
Extremal Black Hole Weather
Claudio Iuliano, Stefan Hollands, Stephen R. Green +1
We consider weakly non-linear gravitational perturbations of a near-extremal Kerr black hole governed by the second order vacuum Einstein equation. Using the GHZ formalism [Green e…
