Rapid localization and inference on compact binary coalescences with the Advanced LIGO-Virgo-KAGRA gravitational-wave detector network
Soichiro Morisaki, Rory Smith, Leo Tsukada +4
We present a rapid parameter estimation framework for compact binary coalescence (CBC) signals observed by the LIGO-Virgo-KAGRA (LVK) detector network. The goal of our framework is…
Rogue echoes from exotic compact objects
Aaron Zimmerman, Richard N. George, Yanbei Chen
Binary systems containing exotic compact objects may emit repeated bursts of gravitational waves (GWs) following coalescence. Such GW echoes would provide a clear signature of new…
In Pursuit of Love: First Templated Search for Compact Objects with Large Tidal Deformabilities in the LIGO-Virgo Data
Horng Sheng Chia, Thomas D. P. Edwards, Digvijay Wadekar +6
We report results on the first matched-filtering search for binaries with compact objects having large tidal deformabilities in the LIGO-Virgo gravitational wave (GW) data. The tid…
Dimensionally Reduced Waveforms for Spin-Induced Quadrupole Searches
Horng Sheng Chia, Thomas D. P. Edwards, Richard N. George +5
We present highly accurate, dimensionally-reduced gravitational waveforms for binary inspirals whose components have large spin-induced quadrupole moments. The spin-induced quadrup…
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…
An approach to computing spectral shifts for black holes beyond Kerr
Asad Hussain, Aaron Zimmerman
Recent measurements of gravitational-wave ringdown following the merger of binary black holes raise the prospect of precision black hole spectroscopy in the near future. To perform…

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…

General-relativistic precession in a black-hole binary
Mark Hannam, Charlie Hoy, Jonathan E. Thompson +24
The general-relativistic phenomenon of spin-induced orbital precession has not yet been observed in strong-field gravity. Gravitational-wave observations of binary black holes (BBH…
Gravitational Wave Timing Array
María José Bustamante-Rosell, Joel Meyers, Noah Pearson +2
We describe the design of a gravitational wave timing array, a novel scheme that can be used to search for low-frequency gravitational waves by monitoring continuous gravitational…
Source properties of the lowest signal-to-noise-ratio binary black hole detections
Yiwen Huang, Carl-Johan Haster, Salvatore Vitale +6
We perform a detailed parameter estimation study of binary black hole merger events reported in Zackay et al. and Venumadhav et al.. These are some of the faintest signals reported…
Prospects for Fundamental Physics with LISA
Enrico Barausse, Emanuele Berti, Thomas Hertog +318
In this paper, which is of programmatic rather than quantitative nature, we aim to further delineate and sharpen the future potential of the LISA mission in the area of fundamental…
The SXS Collaboration catalog of binary black hole simulations
Michael Boyle, Daniel Hemberger, Dante A. B. Iozzo +37
Accurate models of gravitational waves from merging black holes are necessary for detectors to observe as many events as possible while extracting the maximum science. Near the tim…
Mitigation of the instrumental noise transient in gravitational-wave data surrounding GW170817
