Multipole moments on the common horizon in a binary-black-hole simulation
Yitian Chen, Prayush Kumar, Neev Khera +8
We construct the covariantly defined multipole moments on the common horizon of an equal-mass, non-spinning, quasicircular binary-black-hole system. We see a strong correlation bet…
Success of the small mass ratio approximation during the final orbits of binary black hole simulations
Sergi Navarro Albalat, Aaron Zimmerman, Matthew Giesler +1
Recent studies have shown the surprising effectiveness of the small mass-ratio approximation (SMR) in modeling the relativistic two-body problem even at comparable masses. Up to no…
Redshift factor and the small mass-ratio limit in binary black hole simulations
Sergi Navarro Albalat, Aaron Zimmerman, Matthew Giesler +1
We present a calculation of the Detweiler redshift factor in binary black hole simulations based on its relation to the surface gravity. The redshift factor has far-reaching applic…
Surrogate model for gravitational wave signals from non-spinning, comparable- to large-mass-ratio black hole binaries built on black hole perturbation theory waveforms calibrated to numerical relativity
Tousif Islam, Scott E. Field, Scott A. Hughes +6
We present a reduced-order surrogate model of gravitational waveforms from non-spinning binary black hole systems with comparable to large mass-ratio configurations. This surrogate…
Targeted large mass ratio numerical relativity surrogate waveform model for GW190814
Jooheon Yoo, Vijay Varma, Matthew Giesler +5
Gravitational wave observations of large mass ratio compact binary mergers like GW190814 highlight the need for reliable, high-accuracy waveform templates for such systems. We pres…
