Hydrodynamic Stability of Cosmological Quark-Hadron Phase Transitions
P. Chris Fragile, Peter Anninos
Recent results from linear perturbation theory suggest that first-order cosmological quark-hadron phase transitions occurring as deflagrations may be ``borderline'' unstable, and t…
New Coordinate Systems for Axisymmetric Black Hole Collisions
S. R. Brandt, P. Walker, P. Anninos
We describe a numerical grid generating procedure to construct new classes of orthogonal coordinate systems that are specially adapted to binary black hole spacetimes. The new coor…
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…
Event Horizons of Numerical Black Holes
Peter Anninos, David Bernstein, Steven Brandt +5
We have developed a powerful and efficient method for locating the event horizon of a black hole spacetime, making possible the study of the dynamics of event horizons in numerical…
Singularity Avoidance in Numerical Black Hole Spacetimes
Peter Anninos, Greg Daues, Joan Masso +2
Spacetime singularities in numerical relativity can be avoided by excising a region of the computational domain from inside the apparent horizon. We report on results of such a sch…
