Black Hole Spectroscopy: Determining Waveforms from 3D Excited Black Holes
Gabrielle Allen, Karen Camarda, Edward Seidel
We present the first results for Cauchy nonlinear evolution of 3D, nonaxisymmetric distorted black holes. We focus on the extraction and verification of 3D waveforms determined by…
Evolution of Distorted Black Holes: A Perturbative Approach
Gabrielle Allen, Karen Camarda, Edward Seidel
We consider a series of distorted black hole initial data sets, and develop techniques to evolve them using the linearized equations of motion for the gravitational wave perturbati…
Three Dimensional Distorted Black Holes: Initial Data and Evolution
S. R. Brandt, K. Camarda, E. Seidel
We present a new class of 3D black hole initial data sets for numerical relativity. These data sets go beyond the axisymmetric, ``gravity wave plus rotating black hole'' single bla…
3D Numerical Relativity at NCSA
Peter Anninos, Karen Camarda, Joan Masso +4
Numerical relativity is finally coming of age with the development of massively parallel computers. 3D problems, which were completely intractable several years ago due to limited…
