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.…
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…
Dynamical Horizon Segments and Spacetime Isometries
Abhay Ashtekar, Badri Krishnan
Given a space-time admitting a dynamical horizon segment (DHS) , we show that there are stringent constraints on the Killing fields that…
Black hole spectroscopy: from theory to experiment
Emanuele Berti, Vitor Cardoso, Gregorio Carullo +65
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…
Spectroscopy for asymmetric binary black hole mergers
Jahed Abedi, Collin D. Capano, Shilpa Kastha +5
We study Bayesian inference of black hole ringdown modes for simulated binary black hole signals. We consider to what extent different fundamental ringdown modes can be identified…
A gating-and-inpainting perspective on GW150914 ringdown overtone: understanding the data analysis systematics
Yi-Fan Wang, Collin D. Capano, Jahed Abedi +5
We revisit the recent debate on the evidence for an overtone in the black hole ringdown of GW150914 using an independent data-analysis pipeline. By gating and inpainting the data,…
