Universality in the Transition from Inspiral to Plunge: 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…
