Matthew Giesler, Sizheng Ma, Keefe Mitman +11
Using high-accuracy numerical relativity waveforms, we confirm the presence of numerous overtones of the , quasinormal mode early in the ringdown of binary black hole…
Simulating binary black hole mergers using discontinuous Galerkin methods
Geoffrey Lovelace, Kyle C. Nelli, Nils Deppe +28
Binary black holes are the most abundant source of gravitational-wave observations. Gravitational-wave observatories in the next decade will require tremendous increases in the acc…

Nils Deppe, Francois Foucart, Marceline S. Bonilla +18
We present a discontinuous Galerkin-finite difference hybrid scheme that allows high-order shock capturing with the discontinuous Galerkin method for general relativistic magnetohy…
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…
Multipole moments on the common horizon in a binary-black-hole simulation
Yitian Chen, Prayush Kumar, Neev Khera +8
We construct the covariantly defined multipole moments on the common horizon of an equal-mass, non-spinning, quasicircular binary-black-hole system. We see a strong correlation bet…
Success of the small mass ratio approximation during the final orbits of binary black hole simulations

Sergi Navarro Albalat, Aaron Zimmerman, Matthew Giesler +1
We present a calculation of the Detweiler redshift factor in binary black hole simulations based on its relation to the surface gravity. The redshift factor has far-reaching applic…
Surrogate model for gravitational wave signals from non-spinning, comparable- to large-mass-ratio black hole binaries built on black hole perturbation theory waveforms calibrated to numerical relativity
Tousif Islam, Scott E. Field, Scott A. Hughes +6
We present a reduced-order surrogate model of gravitational waveforms from non-spinning binary black hole systems with comparable to large mass-ratio configurations. This surrogate…
Targeted large mass ratio numerical relativity surrogate waveform model for GW190814
Jooheon Yoo, Vijay Varma, Matthew Giesler +5
Gravitational wave observations of large mass ratio compact binary mergers like GW190814 highlight the need for reliable, high-accuracy waveform templates for such systems. We pres…
Search of the Early O3 LIGO Data for Continuous Gravitational Waves from the Cassiopeia A and Vela Jr. Supernova Remnants
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1411
We present directed searches for continuous gravitational waves from the neutron stars in the Cassiopeia A (Cas A) and Vela Jr. supernova remnants. We carry out the searches in the…
Simulating magnetized neutron stars with discontinuous Galerkin methods
Nils Deppe, François Hébert, Lawrence E. Kidder +33
Discontinuous Galerkin methods are popular because they can achieve high order where the solution is smooth, because they can capture shocks while needing only nearest-neighbor com…
