Computation of Displacement and Spin Gravitational Memory in Numerical Relativity

no code implementations22 Jul 2020 Keefe Mitman, Jordan Moxon, Mark A. Scheel, Saul A. Teukolsky, Michael Boyle, Nils Deppe, Lawrence E. Kidder, William Throwe

We also perform a separate calculation of the memory using equations for the Bondi-Metzner-Sachs charges as well as the energy and angular momentum fluxes at asymptotic infinity.

Improved Cauchy-characteristic evolution system for high-precision numerical relativity waveforms

1 code implementation2 Jul 2020 Jordan Moxon, Mark A. Scheel, Saul A. Teukolsky

We present several improvements to the Cauchy-characteristic evolution procedure that generates high-fidelity gravitational waveforms at $\mathcal{I}^+$ from numerical relativity simulations.

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.
