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.…

Numerical self-force calculations for scalar particles, formulated in the lab frame

Stamatis Vretinaris, Erik Schnetter, Badri Krishnan

We derive equations of motion for scalar particles self-consistently interacting with a scalar field,including the radiation produced by the particles' acceleration. Our approach d…

Cusp Formation in Merging Black Hole Horizons

Shilpa Kastha, Stamatis Vretinaris, Daniel Pook-Kolb +1

An important question in binary black hole mergers is to connect properties of the remnant black hole to those of the two initial black holes. These properties include not only the…

Asymptotics and Universality in Black Holes: from the quasinormal Weyl's law to the binary merger waveform

José Luis Jaramillo, Lamis Al Sheikh, Jérémy Besson +7

Current state-of-the-art approaches to black hole (BH) dynamics, encompassing several effective approximation schemes, offer a remarkable control of the quantitative aspects of str…

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…

Quasi-Local Black Hole Horizons: Recent Advances

Abhay Ashtekar, Badri Krishnan

While the early literature on black holes focused on event horizons, subsequently it was realized that their teleological nature makes them unsuitable for many physical application…
