Gravitational Wave Extraction - A Benchmark?

Abstract
Gravitational wave extraction is one of the important aspects of the
computational grand challenge program. There are two schools of
thought when it comes to implementing the extraction of gravitational
waves from a numerically generated spacetime. One way is to simply let
the waves propogate via standard Cauchy devolopment (evolving spatial
surfaces using the standard initial value formulation). One of the
major drawbacks with this method is that a very large computational
grid is needed to allow the waves to propogate far from the source.
The other way to study radiation far from the source is to use an
initial value formulation based on ``characteristic surfaces.''
This paper is a summary of the paper by Gomez et. al. It is
written for computer scientists working on the computational grand
challenge program ``Black Hole Binaries: Coalescence and Gravitational
Radiation.''
