NRSur7dq4v2: A multi-domain precessing surrogate model with improved accuracy
Abhishek Ravishankar, Vijay Varma, Scott E. Field +5
Numerical relativity simulations provide the most accurate waveforms for binary black hole coalescences, but are prohibitively expensive for direct use in gravitational-wave data a…
Fast, accurate, and differentiable: a neural-network surrogate for NRSur7dq4 precessing binary black hole waveforms
Michael Pürrer, Ashwin Girish, Lucy M. Thomas +2
We present a neural network surrogate model that emulates the NRSur7dq4 gravitational waveform model for precessing binary black hole mergers. The surrogate decomposes the waveform…
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…
Radiation outer boundary conditions and near-to-far field signal transformations for the Bardeen-Press equation
Som Dev Bishoyi, Scott E. Field, Stephen R. Lau
Several theoretical and astrophysical problems - including gravitational-wave modeling for extreme mass-ratio inspirals - require accurate time-domain solutions of the spin-weight…
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…
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…
