A Parallel Adaptive Event Horizon Finder for Numerical Relativity

Understand

With Advanced LIGO detecting the gravitational waves emitted from a pair of merging black holes in late 2015, we have a new perspective into the strong field regime of binary black hole systems.

• Event horizons are the defining features of such black hole spacetimes.
• We introduce a new code for locating event horizons in numerical simulations based on a Delaunay triangulation on a topological sphere.
• The code can automatically refine arbitrary regions of the event horizon surface to find and explore features such as the hole in a toroidal event horizon, as discussed in our companion paper.
