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…
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…
Learning Post-Newtonian Corrections from Numerical Relativity
Jooheon Yoo, Michael Boyle, Nils Deppe
Accurate modeling of gravitational waveforms from compact binary coalescences remains central to gravitational-wave (GW) astronomy. Post-Newtonian (PN) approximations capture the e…
Error quantification and comparison of binary neutron star gravitational waveforms from numerical relativity codes
Sarah Habib, Elias R. Most, Nils Deppe +11
Future gravitational wave detections of merging binary neutron star systems have the possibility to tightly constrain the equation of state of dense nuclear matter. In order to ext…
