Contribution

It presents the first numerical construction of rotating Randall-Sundrum black holes in 5 dimensions using perturbative techniques.

Findings

Good agreement with previous results for non-rotating black holes.

First numerical results for rotating Randall-Sundrum black holes.

Rotating black holes have larger horizon area than Myers-Perry black holes of same mass and angular momentum.

Abstract

We numerically construct large Randall-Sundrum II brane black holes in 4 and 5 dimensions from associated AdS/CFT spacetimes. Our solutions are leading order perturbations of a representative of the boundary conformal structure of the AdS spacetime sourced by the dual CFT stress tensor. The 4-dimensional solutions are static perturbations of the Euclidean Schwarzschild metric, while the 5-dimensional solutions are perturbations of the Myers-Perry metric with equal angular momenta. We compare the former with previous numerical results for Randall-Sundrum bulk black holes and find good agreement down to a horizon radius of about rH ~30l. The latter are the first numerical results pertaining to rotating Randall-Sundrum black holes. They have the same entropy, but a larger horizon area than Myers-Perry black holes of the same mass and angular momentum.
