Black Hole Ringdown Spectroscopy for Precessing Binary Black Hole Coalescences
Gravitational waves offer a unique window for probing gravity in the most dynamical regime. In particular, the ringdown of an astrophysical black hole encodes information about the properties of the remnant and the progenitor binary. In this talk, I present a phenomenological model of the quasinormal modes that are excited in the ringdowns of comparable mass, quasi-circular precessing binary black hole coalescences, which accurately describes the ringdown phases of a large numerical relativity catalog. This result builds upon previous works on waveform modeling and can be potentially used to improve existing waveform models.
