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…
Relieving scale disparity in binary black hole simulations
Nikolas A. Wittek, Leor Barack, Harald P. Pfeiffer +7
Worldtube excision is a method of reducing computational burden in Numerical Relativity simulations of binary black holes in situations where there is a good analytical model of th…
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…
