Search for Eccentric Black Hole Coalescences during the Third Observing Run of LIGO and Virgo

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1772

Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Or…

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…

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…
