Cosmic censorship violation in black hole collisions in higher dimensions

13.06.2019 14:30 – 15:30

We argue that cosmic censorship is violated in the collision of two black holes in high spacetime dimension D when the initial total angular momentum is sufficiently large. The two black holes merge and form an unstable bar-like horizon, which grows a neck in its middle that pinches down with diverging curvature. The phenomenon is demonstrated using simple numerical simulations of the effective theory in the 1/D expansion.
