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…
