Accurate initial data for Cauchy-characteristic evolution
Guido Da Re, Keefe Mitman, Leo C. Stein +7
Accurate gravitational-wave (GW) templates from numerical-relativity (NR) simulations are essential for GW science. These templates are typically computed at finite radii and extra…
Calculating gravitational waves at infinity: the missing link
Guido Da Re, Keefe Mitman, Leo C. Stein +7
Gravitational-wave science requires waveform templates to be computed at future null infinity, the asymptotic boundary of spacetime. Numerical solutions of Einstein's equations typ…
NRSur7dq4v2: A multi-domain precessing surrogate model with improved accuracy
Abhishek Ravishankar, Vijay Varma, Scott E. Field +5
Numerical relativity simulations provide the most accurate waveforms for binary black hole coalescences, but are prohibitively expensive for direct use in gravitational-wave data a…
High-accuracy drivers to simulate black hole binaries beyond general relativity with the fixing-the-equations approach
Guillermo Lara, Harald P. Pfeiffer, Nils Deppe +9
We implement the "fixing-the-equations" approach [Phys.Rev.D 96 (2017) 8, 084043] in spectre, an NR code using a pseudo-spectral discontinuous Galerkin scheme, to produce long and…
Towards long and accurate numerical relativity waveforms of binary black holes beyond general relativity
Guillermo Lara, Harald P. Pfeiffer, Nils Deppe +9
Numerical relativity (NR) simulations of compact binaries in theories beyond general relativity (GR) will be pivotal for the continued development of future tests of gravity with g…
Eccentricity as a signature of hierarchical subsolar-mass mergers in collapsar disks
Jiaxi Wu, Elias R. Most, Nils L. Vu +4
In this work, we investigate gravitational-wave signatures of a proposed subsolar-mass merger scenario resulting from fragmentation inside a collapsar accretion disk. This scenario…
Merger remnant and eccentricity dynamics surrogates for eccentric nonspinning black hole binaries
Adhrit Ravichandran, Peter James Nee, Keefe Mitman +22
Accurate models of merger remnants are increasingly important for gravitational-wave science, including precision tests of gravity with ringdown, inference of black-hole population…
