Test-beds and applications for apparent horizon finders in numerical relativity
M. Alcubierre, S. Brandt, B. Bruegmann +4
We present a series of test beds for numerical codes designed to find apparent horizons. We consider three apparent horizon finders that use different numerical methods: one of the…

Head--on Collision of Two Unequal Mass Black Holes
Peter Anninos, Steven Brandt
We present results from the first fully nonlinear numerical calculations of the head--on collision of two unequal mass black holes. Selected waveforms of the most dominant l=2, 3 a…

Stable characteristic evolution of generic 3-dimensional single-black-hole spacetimes
The Binary Black Hole Grand Challenge Alliance, :, R. Gomez +42
We report new results which establish that the accurate 3-dimensional numerical simulation of generic single-black-hole spacetimes has been achieved by characteristic evolution wit…
