Chaos and fractals of the black hole photon ring
The photon ring of a Kerr black hole decomposes into a self-similar hierarchy of subrings. Here, we show that this self-similar structure persists in pha...
Parameter matching between horizon quasi-local and point-particle definitions at 1PN for quasi-circular and non spinning BBH systems in harmonic gauge
We investigate how commonly used parameter definitions in Post-Newtonian (PN) theory compare with those from Numerical Relativity (NR) for binary black h...
Black hole spectroscopy: from theory to experiment
The “ringdown” radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of bla...
The SXS Collaboration’s third catalog of binary black hole simulations
We present a major update to the Simulating eXtreme Spacetimes (SXS) Collaboration’s catalog of binary black hole simulations. Using highly efficient spe...
GWSurrogate: A Python package for gravitational wave surrogate models
Fast and accurate waveform models are fundamentally important to modern gravitational wave astrophysics, enabling the study of merging compact objects li...
