Accurate Evolutions of Orbiting Black Hole Binaries Without Excision

ORAL

Abstract

We present a new technique for evolving moving black holes without excision. Our technique, which is based on a regularization of the standard `puncture' approach to the BSSN evolution system, allows for stable evolution of orbiting black-hole binaries. We used this technique to evolve a set of pre-ISCO binaries and show the resulting waveforms as well as the tracks of the individual horizons.
