Radiation outer boundary conditions and near-to-far field signal transformations for the Bardeen-Press equation
Som Dev Bishoyi, Scott E. Field, Stephen R. Lau
Several theoretical and astrophysical problems - including gravitational-wave modeling for extreme mass-ratio inspirals - require accurate time-domain solutions of the spin-weight…
Fast evaluation of far-field signals for time-domain wave propagation
Scott E. Field, Stephen R. Lau
Time-domain simulation of wave phenomena on a finite computational domain often requires a fictitious outer boundary. An important practical issue is the specification of appropria…
Fast evaluation of asymptotic waveforms from gravitational perturbations
Alex G. Benedict, Scott E. Field, Stephen R. Lau
In the context of blackhole perturbation theory, we describe both exact evaluation of an asymptotic waveform from a time series recorded at a finite radial location and its numeric…
Sparse spectral-tau method for the three-dimensional helically reduced wave equation on two-center domains
Stephen R. Lau, Richard H. Price
We describe a multidomain spectral-tau method for solving the three-dimensional helically reduced wave equation on the type of two-center domain that arises when modeling compact b…
Implicit-explicit (IMEX) evolution of single black holes
Stephen R. Lau, Geoffrey Lovelace, Harald P. Pfeiffer
Numerical simulations of binary black holes---an important predictive tool for the detection of gravitational waves---are computationally expensive, especially for binaries with hi…
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…
