Revisiting the Coprecessing Frame in the Presence of Orbital Eccentricity
Lucy M. Thomas, Katerina Chatziioannou, Sam Johar +2
Accurate inclusion of both spin precession and orbital eccentricity effects in gravitational waveform models represents a key hurdle in our ability to fully characterize the proper…
No hair but plenty of feathers: are birds black holes?
Andrew Laeuger, Taylor Knapp
The imitative verb "chirp" is thought to originate from 16th-century Middle English. Meanwhile, this same word has been used to describe the gravitational waves (GWs) emitted from…
Model-agnostic gravitational-wave background characterization algorithm
Taylor Knapp, Patrick M. Meyers, Arianna I. Renzini
As ground-based gravitational-wave (GW) detectors improve in sensitivity, gravitational-wave background (GWB) signals will progressively become detectable. Currently, searches for…
The SXS Collaboration's third catalog of binary black hole simulations
Mark A. Scheel, Michael Boyle, Keefe Mitman +56
We present a major update to the Simulating eXtreme Spacetimes (SXS) Collaboration's catalog of binary black hole simulations. Using highly efficient spectral methods implemented i…
Parameter control for eccentric, precessing binary black hole simulations with SpEC
Taylor Knapp, Katerina Chatziioannou, Harald Pfeiffer +2
Numerical relativity simulations of merging black holes provide the most accurate description of the binary dynamics and the emitted gravitational wave signal. However, practical c…
