Black Hole Excision with Multiple Grid Patches
Jonathan Thornburg
When using black hole excision to numerically evolve a black hole spacetime with no continuous symmetries, most 3+1 finite differencing codes use a Cartesian grid. It's difficult t…
Episodic Self-Similarity in Critical Gravitational Collapse
J. Thornburg, Ch. Lechner, M. Purrer +2
We report on a new behavior found in numerical simulations of spherically symmetric gravitational collapse in self-gravitating SU(2) sigma models at intermediate gravitational coup…
A Multiple-Grid-Patch Evolution Scheme for 3-D Black Hole Excision
Jonathan Thornburg
When using black hole excision to numerically evolve a fully generic black hole spacetime, most 3-D 3+1 codes use an -topology (spatial) grid. In such a grid, an $r = \constan…
A 3+1 Computational Scheme for Dynamic Spherically Symmetric Black Hole Spacetimes -- II: Time Evolution
Jonathan Thornburg
This is the second in a series of papers describing a 3+1 computational scheme for the numerical simulation of dynamic black hole spacetimes. We discuss the numerical time-evolutio…
