Accurate waveforms for generic planar-orbit binary black holes: The multipolar effective-one-body model SEOBNRv6EHM

Aldo Gamboa, Alessandra Buonanno, Lorenzo Pompili +8

Accurate and computationally efficient waveform models are required to infer the parameters of compact binaries from their gravitational wave (GW) emission. Among these parameters,…

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…

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…
