Universality in the Transition from Inspiral to Plunge for Extreme-Mass-Ratio-Inspirals: High-Accuracy Analytic Solutions and Catastrophe Theory

Ariadna Ribes Metidieri, Béatrice Bonga, Badri Krishnan +1

We revisit the transition from inspiral to plunge for extreme mass-ratio inspirals on quasi-circular, inclined orbits in Kerr spacetime from the perspective of catastrophe theory.…

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…

Wave optics for rotating stars

Béatrice Bonga, Job Feldbrugge, Ariadna Ribes Metidieri

Gravitational lensing in wave optics is a rich field combining caustic singularities, general relativity and interference phenomena. We present a detailed evaluation of wave optics…

Tidal deformations of slowly spinning isolated horizons

A. Ribes Metidieri, B. Bonga, B. Krishnan

It is generally believed that tidal deformations of a black hole in an external field, as measured using its gravitational field multipoles, vanish. However, this does not mean tha…

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…
