ABSTRACT:

We will briefly review the breakthrough in numerical relativity that allowed the long term evolutions of black holes. Application of these techniques allowed the discovery and modeling of the recoil velocities, masses and spins acquired by the merger remnant. Recoil velocities of up to 4000 km/s are predicted for binary black hole mergers leading to potential scape of supermassive black holes from their host galaxies. Spin orbit interactions, precesion and spin flips are also studied. Mathematical aspects of General Relativity such as the cosmic censorship, isolated horizon formulae and no hair theorem are also tested numerically. The numerical evolution technique has also been extended to deal with three and N black hole close encounters.
