Black Hole Spectroscopy for Precessing Binary Black Hole Coalescences
Hengrui Zhu, Harrison Siegel, Keefe Mitman +14
The spectroscopic study of black hole quasinormal modes in gravitational-wave ringdown observations is hindered by our ignorance of which modes should dominate astrophysical signal…
Formulation Improvements for Critical Collapse Simulations
Daniela Cors, Sarah Renkhoff, Hannes R. Rüter +2
The precise tuning required to observe critical phenomena in gravitational collapse poses a challenge for most numerical codes. First, threshold estimation searches may be obstruct…
Fully relativistic three-dimensional Cauchy-characteristic matching for physical degrees of freedom
Sizheng Ma, Jordan Moxon, Mark A. Scheel +8
A fully relativistic three-dimensional Cauchy-characteristic matching (CCM) algorithm is implemented for physical degrees of freedom in a numerical relativity code SpECTRE. The met…
Extending black-hole remnant surrogate models to extreme mass ratios
Matteo Boschini, Davide Gerosa, Vijay Varma +19
Numerical-relativity surrogate models for both black-hole merger waveforms and remnants have emerged as important tools in gravitational-wave astronomy. While producing very accura…
A positivity-preserving adaptive-order finite-difference scheme for GRMHD
Nils Deppe, Lawrence E. Kidder, Saul A. Teukolsky +6
We present an adaptive-order positivity-preserving conservative finite-difference scheme that allows a high-order solution away from shocks and discontinuities while guaranteeing p…
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…
Worldtube excision method for intermediate-mass-ratio inspirals: scalar-field model in 3+1 dimensions
Nikolas A. Wittek, Mekhi Dhesi, Leor Barack +10
Binary black hole simulations become increasingly more computationally expensive with smaller mass ratios, partly because of the longer evolution time, and partly because the lengt…
Laying the foundation of the effective-one-body waveform models SEOBNRv5: improved accuracy and efficiency for spinning non-precessing binary black holes
Lorenzo Pompili, Alessandra Buonanno, Héctor Estellés +21
We present SEOBNRv5HM, a more accurate and faster inspiral-merger-ringdown gravitational waveform model for quasi-circular, spinning, nonprecessing binary black holes within the ef…
