Numerical simulation of orbiting black holes
Bernd Bruegmann, Wolfgang Tichy, Nina Jansen
We present numerical simulations of binary black hole systems which for the first time last for about one orbital period for close but still separate black holes as indicated by th…

Numerical stability of the AA evolution system compared to the ADM and BSSN systems
Nina Jansen, Bernd Bruegmann, Wolfgang Tichy
We explore the numerical stability properties of an evolution system suggested by Alekseenko and Arnold. We examine its behavior on a set of standardized testbeds, and we evolve a…
