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…
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…
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…
Worldtube excision method for intermediate-mass-ratio inspirals: self-consistent evolution in a scalar-charge model
Nikolas A. Wittek, Adam Pound, Harald P. Pfeiffer +1
This is a third installment in a program to develop a method for alleviating the scale disparity in binary black hole simulations with mass ratios in the intermediate astrophysical…
Scalarization of isolated black holes in scalar Gauss-Bonnet theory in the fixing-the-equations approach
Guillermo Lara, Harald P. Pfeiffer, Nikolas A. Wittek +6
One of the most promising avenues to perform numerical evolutions in theories beyond General Relativity is the fixing-the-equations approach, a proposal in which new ``driver'' equ…
Worldtube excision method for intermediate-mass-ratio inspirals: scalar-field model in 3+1 dimensions
Nikolas A. Wittek, Mekhi Dhesi, Leor Barack +10
Binary black hole simulations become increasingly more computationally expensive with smaller mass ratios, partly because of the longer evolution time, and partly because the lengt…
A scalable elliptic solver with task-based parallelism for the SpECTRE numerical relativity code
Nils L. Vu, Harald P. Pfeiffer, Gabriel S. Bonilla +10
Elliptic partial differential equations must be solved numerically for many problems in numerical relativity, such as initial data for every simulation of merging black holes and n…
Simulating magnetized neutron stars with discontinuous Galerkin methods
Nils Deppe, François Hébert, Lawrence E. Kidder +33
Discontinuous Galerkin methods are popular because they can achieve high order where the solution is smooth, because they can capture shocks while needing only nearest-neighbor com…
