Fast prediction and evaluation of gravitational waveforms using surrogate models
Scott E. Field, Chad R. Galley, Jan S. Hesthaven +2
[Abridged] We propose a solution to the problem of quickly and accurately predicting gravitational waveforms within any given physical model. The method is relevant for both real-t…
Numerical simulations with a first order BSSN formulation of Einstein's field equations
J. David Brown, Peter Diener, Scott E. Field +7
We present a new fully first order strongly hyperbolic representation of the BSSN formulation of Einstein's equations with optional constraint damping terms. We describe the charac…
Reduced basis catalogs for gravitational wave templates
Scott E. Field, Chad R. Galley, Frank Herrmann +3
We introduce a reduced basis approach as a new paradigm for modeling, representing and searching for gravitational waves. We construct waveform catalogs for non-spinning compact bi…
Discontinuous Galerkin method for the spherically reduced BSSN system with second-order operators
Scott E. Field, Jan S. Hesthaven, Stephen R. Lau +1
We present a high-order accurate discontinuous Galerkin method for evolving the spherically-reduced Baumgarte-Shapiro-Shibata-Nakamura (BSSN) system expressed in terms of second-or…
Persistent junk solutions in time-domain modeling of extreme mass ratio binaries
Scott E. Field, Jan S. Hesthaven, Stephen R. Lau
In the context of metric perturbation theory for non-spinning black holes, extreme mass ratio binary (EMRB) systems are described by distributionally forced master wave equations.…
Discontinuous Galerkin method for computing gravitational waveforms from extreme mass ratio binaries
Scott E. Field, Jan S. Hesthaven, Stephen R. Lau
Gravitational wave emission from extreme mass ratio binaries (EMRBs) should be detectable by the joint NASA-ESA LISA project, spurring interest in analytical and numerical methods…
IMEX evolution of scalar fields on curved backgrounds
Stephen R. Lau, Harald P. Pfeiffer, Jan S. Hesthaven
Inspiral of binary black holes occurs over a time-scale of many orbits, far longer than the dynamical time-scale of the individual black holes. Explicit evolutions of a binary syst…
