Merger remnant and eccentricity dynamics surrogates for eccentric nonspinning black hole binaries

Adhrit Ravichandran, Peter James Nee, Keefe Mitman +22

Accurate models of merger remnants are increasingly important for gravitational-wave science, including precision tests of gravity with ringdown, inference of black-hole population…

Including higher-order modes in a quadrupolar eccentric numerical relativity surrogate using universal eccentric modulation functions

Tousif Islam, Adhrit Ravichandran, Peter James Nee +15

\texttt{gwNRHME} is a framework that converts multi-modal (i.e., containing several spherical harmonic modes) quasi-circular waveforms into their eccentric counterparts, provided t…

Chase Orbits, not Time: A Scalable Paradigm for Long-Duration Eccentric Gravitational-Wave Surrogates

Akash Maurya, Prayush Kumar, Scott E. Field +6

Orbital eccentricity is a key tracer of the astrophysical origins of compact binaries. Yet it remains absent from routine LIGO-Virgo-KAGRA analyses, in part because of the prohibit…

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…

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…

GWSurrogate: A Python package for gravitational wave surrogate models

Scott E. Field, Vijay Varma, Jonathan Blackman +9

Fast and accurate waveform models are fundamentally important to modern gravitational wave astrophysics, enabling the study of merging compact objects like black holes and neutron…
