Surrogate model of hybridized numerical relativity binary black hole waveforms

1 code implementation19 Dec 2018 Vijay Varma, Scott E. Field, Mark A. Scheel, Jonathan Blackman, Lawrence E. Kidder, Harald P. Pfeiffer

We present NRHybSur3dq8, a surrogate model for hybridized nonprecessing numerical relativity waveforms, that is valid for the entire LIGO band (starting at $20~\text{Hz}$) for stellar mass binaries with total masses as low as $2. 25\, M_{\odot}$.

Constraining the parameters of GW150914 & GW170104 with numerical relativity surrogates

1 code implementation24 Aug 2018 Prayush Kumar, Jonathan Blackman, Scott E. Field, Mark Scheel, Chad R. Galley, Michael Boyle, Lawrence E. Kidder, Harald P. Pfeiffer, Bela Szilagyi, Saul A. Teukolsky

In this paper we demonstrate the viability of these surrogate models as reliable parameter estimation tools, and show that within a fully Bayesian framework surrogates can help us extract more information from gravitational wave observations than traditional models.

A Numerical Relativity Waveform Surrogate Model for Generically Precessing Binary Black Hole Mergers

1 code implementation19 May 2017 Jonathan Blackman, Scott E. Field, Mark A. Scheel, Chad R. Galley, Christian D. Ott, Michael Boyle, Lawrence E. Kidder, Harald P. Pfeiffer, Béla Szilágyi

A generic, non-eccentric binary black hole (BBH) system emits gravitational waves (GWs) that are completely described by 7 intrinsic parameters: the black hole spin vectors and the ratio of their masses.

A Surrogate Model of Gravitational Waveforms from Numerical Relativity Simulations of Precessing Binary Black Hole Mergers

no code implementations2 Jan 2017 Jonathan Blackman, Scott E. Field, Mark A. Scheel, Chad R. Galley, Daniel A. Hemberger, Patricia Schmidt, Rory Smith

We present the first surrogate model for gravitational waveforms from the coalescence of precessing binary black holes.

Fast prediction and evaluation of gravitational waveforms using surrogate models

no code implementations16 Aug 2013 Scott E. Field, Chad R. Galley, Jan S. Hesthaven, Jason Kaye, Manuel Tiglio

Our approach is based on three offline steps resulting in an accurate reduced-order model that can be used as a surrogate for the true/fiducial waveform family.
