Cross section, final spin and zoom-whirl behavior in high-energy black hole collisions
Published 7 Jul 2009 in gr-qc and hep-th | (0907.1252v2)
Abstract: We study the collision of two highly boosted equal mass, nonrotating black holes with generic impact parameter. We find such systems to exhibit zoom-whirl behavior when fine tuning the impact parameter. Near the threshold of immediate merger the remnant black hole Kerr parameter can be near maximal (a/M about 0.95) and the radiated energy can be as large as 35% of the center-of-mass energy.
