Theory-agnostic searches for non-gravitational modes in black hole ringdown
Francesco Crescimbeni, Xisco Jimenez Forteza, Swetha Bhagwat +2
In any extension of General Relativity (GR), extra fundamental degrees of freedom couple to gravity. Besides deforming GR forecasts in a theory-dependent way, this coupling generic…
Ringdown mode amplitudes of precessing binary black holes
Francesco Nobili, Swetha Bhagwat, Costantino Pacilio +1
The ringdown phase of a binary black-hole merger encodes key information about the remnant properties and provides a direct probe of the strong-field regime of General Relativity.…
The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
Black hole spectroscopy: from theory to experiment
Emanuele Berti, Vitor Cardoso, Gregorio Carullo +70
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…
Flexible mapping of ringdown amplitudes for nonprecessing binary black holes
Costantino Pacilio, Swetha Bhagwat, Francesco Nobili +1
The remnant black hole from a binary coalescence emits ringdown gravitational waves characterized by quasinormal modes, which depend solely on the remnant's mass and spin. In contr…
Simulation-based inference of black hole ringdowns in the time domain
Costantino Pacilio, Swetha Bhagwat, Roberto Cotesta
Gravitational waves emitted by a ringing black hole allow us to perform precision tests of general relativity in the strong field regime. With improvements to our current gravitati…
