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…
Signatures from metastable oppositely-charged black hole binaries in scalar Gauss-Bonnet gravity
Guillermo Lara, Maxence Corman, Peter James Nee +14
We conduct numerical simulations of inspiraling, oppositely-charged black holes in the class of scalar-Gauss-Bonnet theories that exhibit spontaneous black hole scalarization. For…
Simulating binary black hole mergers using discontinuous Galerkin methods
Geoffrey Lovelace, Kyle C. Nelli, Nils Deppe +28
Binary black holes are the most abundant source of gravitational-wave observations. Gravitational-wave observatories in the next decade will require tremendous increases in the acc…
