Implementation of higher-order absorbing boundary conditions for the Einstein equations
Oliver Rinne, Luisa T. Buchman, Mark A. Scheel +1
We present an implementation of absorbing boundary conditions for the Einstein equations based on the recent work of Buchman and Sarbach. In this paper, we assume that spacetime ma…
High-accuracy waveforms for binary black hole inspiral, merger, and ringdown
Mark A. Scheel, Michael Boyle, Tony Chu +3
The first spectral numerical simulations of 16 orbits, merger, and ringdown of an equal-mass non-spinning binary black hole system are presented. Gravitational waveforms from these…
Evolving black hole-neutron star binaries in general relativity using pseudospectral and finite difference methods
Matthew D. Duez, Francois Foucart, Lawrence E. Kidder +3
We present a code for solving the coupled Einstein-hydrodynamics equations to evolve relativistic, self-gravitating fluids. The Einstein field equations are solved in generalized h…
Revisiting Event Horizon Finders
Michael I. Cohen, Harald P. Pfeiffer, Mark A. Scheel
Event horizons are the defining physical features of black hole spacetimes, and are of considerable interest in studying black hole dynamics. Here, we reconsider three techniques t…
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…
Binary-black-hole initial data with nearly-extremal spins
Geoffrey Lovelace, Robert Owen, Harald P. Pfeiffer +1
There is a significant possibility that astrophysical black holes with nearly-extremal spins exist. Numerical simulations of such systems require suitable initial data. In this pap…
