Spherical Harmonic Amplitudes From Grid Data
Mark E. Rupright
The problem of resolving spherical harmonic components from numerical data defined on a rectangular grid has many applications, particularly for the problem of gravitational radiat…
Cauchy-perturbative matching and outer boundary conditions: computational studies
Luciano Rezzolla, Andrew M. Abrahams, Richard A. Matzner +2
We present results from a new technique which allows extraction of gravitational radiation information from a generic three-dimensional numerical relativity code and provides stabl…
Cauchy-perturbative matching and outer boundary conditions I: Methods and tests
M. E. Rupright, A. M. Abrahams, L. Rezzolla
We present a new method of extracting gravitational radiation from three-dimensional numerical relativity codes and providing outer boundary conditions. Our approach matches the so…
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…
Boosted three-dimensional black-hole evolutions with singularity excision
The Binary Black Hole Grand Challenge Alliance, :, G. B. Cook +43
Binary black hole interactions provide potentially the strongest source of gravitational radiation for detectors currently under development. We present some results from the Binar…
Gravitational wave extraction and outer boundary conditions by perturbative matching
The Binary Black Hole Grand Challenge Alliance, :, A. M. Abrahams +42
We present a method for extracting gravitational radiation from a three-dimensional numerical relativity simulation and, using the extracted data, to provide outer boundary conditi…
