1) High energy black hole collisions

The collision of two boosted black holes (v=0.75c in the center of mass frame) with a finite impact parameter in asymptotically flat spacetime[1]. The intensity of the color refers to the amplitude of the gravitational waves as measured by Ψ4. About 24% of the center of mass frame can be released as radiation, for this collision. The final hole is nearly maximally spinning.
