Numerical Simulations of Oscillating Soliton Stars: Excited States in Spherical Symmetry and Ground State Evolutions in 3D
Jayashree Balakrishna, Ruxandra Bondarescu, Gregory Daues +1
Excited state soliton stars are studied numerically for the first time. The stability of spherically symmetric S-branch excited state oscillatons under radial perturbations is inve…

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…
