Numerical-relativity surrogate modeling with nearly extremal black-hole spins
Marissa Walker, Vijay Varma, Geoffrey Lovelace +1
Numerical relativity (NR) simulations of binary black hole (BBH) systems provide the most accurate gravitational wave predictions, but at a high computational cost -- especially wh…
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…
A fully precessing higher-mode surrogate model of effective-one-body waveforms
Bhooshan Gadre, Michael Pürrer, Scott E. Field +2
We present a surrogate model of \texttt{SEOBNRv4PHM}, a fully precessing time-domain effective-one-body waveform model including subdominant modes. We follow an approach similar to…
Evidence of large recoil velocity from a black hole merger signal
Vijay Varma, Sylvia Biscoveanu, Tousif Islam +6
The final black hole left behind after a binary black hole merger can attain a recoil velocity, or a "kick", reaching values up to 5000 km/s. This phenomenon has important implicat…
