Living Reviews in Relativity is a peer-refereed, solely online physics journal publishing invited reviews covering all areas of relativity research. Reviews are kept up to date by their authors. All reference information is collected into a searchable database. Living Reviews in Relativity is a free resource to the scientific community. Published by the Max Planck Institute for Gravitational Physics (Albert Einstein Institute), Potsdam,...Event and Apparent Horizon Finders for 3+1 Numerical Relativity- June 1, 2007 Event and apparent horizons are key diagnostics for the presence and properties of black holes. In this article I review numerical algorithms and codes for finding event and apparent horizons in numerically-computed spacetimes, focusing on calculations done using the 3+1 ADM formalism. The event horizon of an asymptotically-flat spacetime is the boundary between those events from which a future-pointing null geodesic can reach future null infinity and those events from which no such geodesic...http://www.livingreviews.org/lrr-2007-3 |
