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…
Numerical simulations of black hole-neutron star mergers in scalar-tensor gravity
Sizheng Ma, Vijay Varma, Leo C. Stein +5
We present a numerical-relativity simulation of a black hole - neutron star merger in scalar-tensor (ST) gravity with binary parameters consistent with the gravitational wave event…
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…
Black hole spectroscopy by mode cleaning
Sizheng Ma, Ling Sun, Yanbei Chen
We formulate a Bayesian framework to analyze ringdown gravitational waves from colliding binary black holes and test the no-hair theorem. The idea hinges on mode cleaning -- reveal…
Using rational filters to uncover the first ringdown overtone in GW150914
Sizheng Ma, Ling Sun, Yanbei Chen
There have been debates in the literature about the existence of the first overtone in the ringdown of GW150914. We develop a novel Bayesian framework to reanalyze the data of this…
