Grazing Collisions of Black Holes via the Excision of Singularities
Steve Brandt, Randall Correll, Roberto Gomez +10
We present the first simulations of non-headon (grazing) collisions of binary black holes in which the black hole singularities have been excised from the computational domain. Ini…
Three-dimensional adaptive evolution of gravitational waves in numerical relativity
Kimberly C. B. New, Dae-Il Choi, Joan M. Centrella +3
Adaptive techniques are crucial for successful numerical modeling of gravitational waves from astrophysical sources such as coalescing compact binaries, since the radiation typical…
Notes on causal differencing in ADM/CADM formulations: a 1D comparison
Luis Lehner, Mijan Huq, David Garrison
Causal differencing has shown to be one of the promising and successful approaches towards excising curvature singularities from numerical simulations of black hole spacetimes. So…
Generic Tracking of Multiple Apparent Horizons with Level Flow
Deirdre M. Shoemaker, Mijan F. Huq, Richard A. Matzner
We report the development of the first apparent horizon locator capable of finding multiple apparent horizons in a ``generic'' numerical black hole spacetime. We use a level-flow m…
Locating Boosted Kerr and Schwarzschild Apparent Horizons
Mijan F. Huq, Matthew W. Choptuik, Richard A. Matzner
We describe a finite-difference method for locating apparent horizons and illustrate its capabilities on boosted Kerr and Schwarzschild black holes. Our model spacetime is given by…
Approximate Analytical Solutions to the Initial Data Problem of Black Hole Binary Systems
P. Marronetti, M. Huq, P. Laguna +4
We present approximate analytical solutions to the Hamiltonian and momentum constraint equations, corresponding to systems composed of two black holes with arbitrary linear and ang…
