Finding Event Horizons in Multiple Black Hole Simulations |
We present results of two event horizon finder schemes for full 3D numerical simulations. Both algorithms evolve null surfaces backwards in time. One of them uses a level-set algorithm to describe full 3D event horizons which was first used by Peter Diener. The other is based on a direct 2D parametrisation of the event horizon for simulations with planar symmetry. Both codes can handle numerical spacetimes which are created by the BAM code. We discuss results for the simulation of the inspiral and collision of three black holes. |
