Numerical relativity surrogate model with memory effects and post-Newtonian hybridization
Jooheon Yoo, Keefe Mitman, Vijay Varma +12
Numerical relativity simulations provide the most precise templates for the gravitational waves produced by binary black hole mergers. However, many of these simulations use an inc…
Fixing the BMS frame of numerical relativity waveforms with BMS charges
Keefe Mitman, Leo C. Stein, Michael Boyle +8
The Bondi-van der Burg-Metzner-Sachs (BMS) group, which uniquely describes the symmetries of asymptotic infinity and therefore of the gravitational waves that propagate there, has…
Quasinormal-mode filters: a new approach to analyze the gravitational-wave ringdown of binary black-hole mergers
Sizheng Ma, Keefe Mitman, Ling Sun +7
We propose two frequency-domain filters to analyze ringdown signals of binary black hole mergers. The first rational filter is constructed based on a set of (arbitrary) quasi-norma…
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…
The SpECTRE Cauchy-characteristic evolution system for rapid, precise waveform extraction
Jordan Moxon, Mark A. Scheel, Saul A. Teukolsky +5
We give full details regarding the new Cauchy-characteristic evolution (CCE) system in SpECTRE. The implementation is built to provide streamlined flexibility for either extracting…
High Precision Ringdown Modeling: Multimode Fits and BMS Frames
Lorena Magaña Zertuche, Keefe Mitman, Neev Khera +12
Quasi-normal mode (QNM) modeling is an invaluable tool for characterizing remnant black holes, studying strong gravity, and testing GR. Only recently have QNM studies begun to focu…
Axisymmetric Hydrodynamics in Numerical Relativity Using a Multipatch Method
Jerred Jesse, Matthew D. Duez, Francois Foucart +7
We describe a method of implementing the axisymmetric evolution of general-relativistic hydrodynamics and magnetohydrodynamics through modification of a multipatch grid scheme. In…
High-accuracy mass, spin, and recoil predictions of generic black-hole merger remnants
Vijay Varma, Davide Gerosa, Leo C. Stein +2
We present accurate fits for the remnant properties of generically precessing binary black holes, trained on large banks of numerical-relativity simulations. We use Gaussian proces…
Black-hole kicks from numerical-relativity surrogate models
Davide Gerosa, François Hébert, Leo C. Stein
Binary black holes radiate linear momentum in gravitational waves as they merge. Recoils imparted to the black-hole remnant can reach thousands of km/s, thus ejecting black holes f…
