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…
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…
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…
High-Precision Ringdown Surrogate Model for Non-Precessing Binary Black Holes
Lorena Magaña Zertuche, Leo C. Stein, Keefe Mitman +11
Highly precise and robust waveform models are required as improvements in detector sensitivity enable us to test general relativity with more precision than ever before. In this wo…
Improved frequency spectra of gravitational waves with memory in a binary-black-hole simulation
Yitian Chen, Michael Boyle, Nils Deppe +9
Numerical relativists can now produce gravitational waveforms with memory effects routinely and accurately. The gravitational-wave memory effect contains very low-frequency compone…
A Review of Gravitational Memory and BMS Frame Fixing in Numerical Relativity
Keefe Mitman, Michael Boyle, Leo C. Stein +8
Gravitational memory effects and the BMS freedoms exhibited at future null infinity have recently been resolved and utilized in numerical relativity simulations. With this, gravita…
Optimizing post-Newtonian parameters and fixing the BMS frame for numerical-relativity waveform hybridizations
Dongze Sun, Michael Boyle, Keefe Mitman +4
Numerical relativity (NR) simulations of binary black holes provide precise waveforms, but are typically too computationally expensive to produce waveforms with enough orbits to co…
Numerical Relativity Multimodal Waveforms using Absorbing Boundary Conditions
Luisa T. Buchman, Matthew D. Duez, Marlo Morales +4
Errors due to imperfect boundary conditions in numerical relativity simulations of binary black holes can produce unphysical reflections of gravitational waves which compromise the…
Striking the right tone: toward a self-consistent framework for measuring black hole ringdowns
Teagan A. Clarke, Maximiliano Isi, Paul D. Lasky +9
The ringdown portion of a binary black hole merger consists of a sum of modes, each containing an infinite number of tones that are exponentially damped sinusoids. In principle, th…
Nonlinear Effects In Black Hole Ringdown From Scattering Experiments I: spin and initial data dependence of quadratic mode coupling
Hengrui Zhu, Justin L. Ripley, Frans Pretorius +13
We investigate quadratic quasinormal mode coupling in black hole spacetime through numerical simulations of single perturbed black holes using both numerical relativity and second-…
