Late-time tails in nonlinear evolutions of merging black holes
Marina De Amicis, Hannes Rüter, Gregorio Carullo +17
We uncover late-time gravitational-wave tails in fully nonlinear 3+1 dimensional numerical relativity simulations of merging black holes, using the highly accurate SpEC code. We ac…
Accurate waveforms for eccentric, aligned-spin binary black holes: The multipolar effective-one-body model SEOBNRv5EHM
Aldo Gamboa, Alessandra Buonanno, Raffi Enficiaud +9
The measurement of orbital eccentricity in gravitational-wave (GW) signals will provide unique insights into the astrophysical origin of binary systems, while ignoring eccentricity…
Overtones and Nonlinearities in Binary Black Hole Ringdowns
Matthew Giesler, Sizheng Ma, Keefe Mitman +11
Using high-accuracy numerical relativity waveforms, we confirm the presence of numerous overtones of the , quasinormal mode early in the ringdown of binary black hole…
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…
Parameter control for eccentric, precessing binary black hole simulations with SpEC
Taylor Knapp, Katerina Chatziioannou, Harald Pfeiffer +2
Numerical relativity simulations of merging black holes provide the most accurate description of the binary dynamics and the emitted gravitational wave signal. However, practical c…
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…
Quasistationary hair for binary black hole initial data in scalar Gauss-Bonnet gravity
Peter James Nee, Guillermo Lara, Harald P. Pfeiffer +1
Recent efforts to numerically simulate compact objects in alternative theories of gravity have largely focused on the time-evolution equations. Another critical aspect is the const…
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…
