Successfully simulated distorted, moving, and spinning black holes
Demonstrated long-term stability of the evolution method
Abstract
We report new results which establish that the accurate 3-dimensional numerical simulation of generic single-black-hole spacetimes has been achieved by characteristic evolution with unlimited long term stability. Our results cover a selection of distorted, moving and spinning single black holes, with evolution times up to 60,000M.
