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…
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…
Characterizing the Directionality of Gravitational Wave Emission from Matter Motions within Core-collapse Supernovae
Michael A. Pajkos, Steven J. VanCamp, Kuo-Chuan Pan +3
We analyze the directional dependence of the gravitational wave (GW) emission from 15 3D neutrino radiation hydrodynamic simulations of core-collapse supernovae. Using spin weighte…
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…
Simulating neutron stars with a flexible enthalpy-based equation of state parametrization in SpECTRE
Isaac Legred, Yoonsoo Kim, Nils Deppe +4
Numerical simulations of neutron star mergers represent an essential step toward interpreting the full complexity of multimessenger observations and constraining the properties of…
