Three Dimensional Distorted Black Holes
Steven Brandt, Karen Camarda, Edward Seidel +1
We present three-dimensional, {\it non-axisymmetric} distorted black hole initial data which generalizes the axisymmetric, distorted, non-rotating [Bernstein93a] and rotating [Bran…
Nonlinear and Perturbative Evolution of Distorted Black Holes. II. Odd-parity Modes
J Baker, S Brandt, M Campanelli +3
We compare the fully nonlinear and perturbative evolution of nonrotating black holes with odd-parity distortions utilizing the perturbative results to interpret the nonlinear resul…
Symmetry without Symmetry: Numerical Simulation of Axisymmetric Systems using Cartesian Grids
M. Alcubierre, S. Brandt, B. Bruegmann +4
We present a new technique for the numerical simulation of axisymmetric systems. This technique avoids the coordinate singularities which often arise when cylindrical or polar-sphe…
Radiation recoil from highly distorted black holes
Steven Brandt, Peter Anninos
We present results from numerical evolutions of single black holes distorted by axisymmetric, but equatorially asymmetric, gravitational (Brill) waves. Net radiated energies, appar…
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…
Numerical evolution of matter in dynamical axisymmetric black hole spacetimes. I. Methods and tests
S. Brandt, J. A. Font, J. M. Ibanez +2
We have developed a numerical code to study the evolution of self-gravitating matter in dynamic black hole axisymmetric spacetimes in general relativity. The matter fields are evol…
