High-accuracy drivers to simulate black hole binaries beyond general relativity with the fixing-the-equations approach
Guillermo Lara, Harald P. Pfeiffer, Nils Deppe +9
The paper implements a fixing‑the‑equations method in the Spectre code to generate accurate numerical‑relativity waveforms for black‑hole binaries in shift‑symmetric scalar Gauss‑B…
Towards long and accurate numerical relativity waveforms of binary black holes beyond general relativity
Guillermo Lara, Harald P. Pfeiffer, Nils Deppe +9
The paper presents long, accurate numerical relativity simulations of equal‑mass, nonspinning binary black holes in shift‑symmetric scalar Gauss‑Bonnet gravity, generating waveform…
Self-force calculations with numerical relativity methods
Nils L. Vu, Nami Nishimura, Thomas Osburn +4
To model gravitational waveforms from extreme mass-ratio inspirals (EMRIs) for the upcoming LISA space mission, gravitational self-force calculations are needed to second order in…
Eccentricity as a signature of hierarchical subsolar-mass mergers in collapsar disks
Jiaxi Wu, Elias R. Most, Nils L. Vu +4
In this work, we investigate gravitational-wave signatures of a proposed subsolar-mass merger scenario resulting from fragmentation inside a collapsar accretion disk. This scenario…
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…
Data-Driven Acceleration of Eccentricity Reduction for Binary Black Hole Simulations
Vittoria Tommasini, Nils L. Vu, Mark A. Scheel +1
Reducing orbital eccentricity in numerical relativity simulations of binary black holes is essential for producing astrophysically relevant gravitational wave models, as many of th…
