Eccentric binary black holes: A new framework for numerical relativity waveform surrogates
Peter James Nee, Adhrit Ravichandran, Scott E. Field +17
Mounting evidence indicates that some of the gravitational wave signals observed by the LIGO/Virgo/KAGRA observatories might arise from eccentric compact object binaries, increasin…
A comprehensive look into the accuracy of SpEC binary black hole waveforms
Taylor Knapp, Katerina Chatziioannou, Keefe Mitman +4
Numerical relativity simulations provide a full description of the dynamics of binary systems, including gravitational radiation. The waveforms produced by these simulations have a…
Biased parameter inference of eccentric, spin-precessing binary black holes
Divyajyoti, Isobel M. Romero-Shaw, Vaishak Prasad +8
While the majority of gravitational wave (GW) events observed by the LIGO and Virgo detectors are consistent with mergers of binary black holes (BBHs) on quasi-circular orbits, som…
Error quantification and comparison of binary neutron star gravitational waveforms from numerical relativity codes
Sarah Habib, Elias R. Most, Nils Deppe +11
Future gravitational wave detections of merging binary neutron star systems have the possibility to tightly constrain the equation of state of dense nuclear matter. In order to ext…
Defining eccentricity for spin-precessing binaries
Md Arif Shaikh, Vijay Varma, Antoni Ramos-Buades +4
Standardizing the definition of eccentricity is necessary for unambiguous inference of the orbital eccentricity of compact binaries from gravitational wave observations. In previou…
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…
Modeling the BMS transformation induced by a binary black hole merger
Guido Da Re, Keefe Mitman, Leo C. Stein +12
Understanding the characteristics of the remnant black hole formed in a binary black hole merger is crucial for conducting gravitational wave astronomy. Typically, models of remnan…
Probing the ringdown perturbation in binary black hole coalescences with an improved quasi-normal mode extraction algorithm
Keefe Mitman, Isabella Pretto, Harrison Siegel +9
Using gravitational waves to probe the geometry of the ringing remnant black hole formed in a binary black hole coalescence is a well-established way to test Einstein's theory of g…
Impact of eccentricity and mean anomaly in numerical relativity mergers
Peter James Nee, Aldo Gamboa, Harald P. Pfeiffer +8
Accurate modelling of black hole binaries is critical to achieve the science goals of gravitational-wave detectors. Modelling such configurations relies strongly on calibration to…
Robustness of extracting quasinormal mode information from black hole merger simulations
Leda Gao, Gregory B. Cook, Lawrence E. Kidder +8
In linear perturbation theory, the ringdown of a gravitational wave (GW) signal is described by a linear combination of quasinormal modes (QNMs). Detecting QNMs from GW signals is…
Length dependence of waveform mismatch: a caveat on waveform accuracy
Keefe Mitman, Leo C. Stein, Michael Boyle +4
The Simulating eXtreme Spacetimes Collaboration's code SpEC can now routinely simulate binary black hole mergers undergoing orbits, with the longest simulations undergoing…
