Rotating black hole spacetimes
… along with a study of their evolutions including apparent horizons, event horizons and gravitational radiation, is presented. These initial data sets represent distorted rotating black holes, and two types of non-rotating black holes with odd-parity radiation distortions. The first has the …

Ricci Time in Lemaître-Tolman Model and Block Universe
… location of the timelike regions relative to the apparent horizon. Based on this idea, we find that the regions where these surfaces become timelike are often close to the apparent horizons, but always outside them, and in particular timelike regions occur outside black holes. They are always …

Applications of Numerical Relativity Beyond Astrophysics
… of gravity. In particular, long, thin black hole horizons are known to be subject to the Gregory–Laflamme instability, and this is expected to result in an eventual violation of the weak cosmic censorship conjecture. A landmark simulation of the black string confirmed this in the Kaluza–Klein …

Novel aspects of the dynamics of binary black-hole mergers
… in the curvature distribution on the common apparent horizon are correlated to the linear momentum acquired by the merger remnant. We propose useful tools for the analysis of black holes in the dynamical and isolated horizon frameworks and shed light on how the final merger of apparent …
