Parameter control for binary black hole initial data
Iago B. Mendes, Nils L. Vu, Oliver Long +2
When numerically solving Einstein's equations for binary black holes (BBH), we must find initial data on a three-dimensional spatial slice by solving constraint equations. The cons…

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…
