Rotating extremal black holes in Einstein-Born-Infeld theory

Journal of High Energy Physics
We construct exact solutions that describe the near horizon region of extremal rotating black holes in Einstein-Born-Infeld theory. Using generalized Komar integrals, we extract the electric charge and angular momentum from the near horizon geometries ...

Observational signatures from horizonless black shells imitating rotating black holes

Journal of High Energy Physics, 2018
In arXiv:1705.10172 it was proposed that string theory replaces Schwarzschild black holes with horizonless thin shells with an AdS interior. In this paper we extend the analysis to slowly rotating black holes, solving the Israel-Lanczos-Sen junction ...

Rotating dilaton black holes [PDF]

Physical Review D, 1992
It is shown that an arbitrarily small amount of angular momentum can qualitatively change the properties of extremal charged black holes coupled to a dilaton. In addition, the gyromagnetic ratio of these black holes is computed and an exact rotating black string solution is presented.

Rotating “black holes” with holes in the horizon [PDF]

Physical Review D, 2006
Kerr-Schild solutions of the Einstein-Maxwell field equations, containing semi-infinite axial singular lines, are investigated. It is shown that axial singularities break up the black hole, forming holes in the horizon. As a result, a tube-like region appears which allows matter to escape from the interior without crossing the horizon.

ROTATING BRANE WORLD BLACK HOLES [PDF]

Modern Physics Letters A, 2002
A five-dimensional rotating black string in a Randall–Sundrum brane world is considered. The black string intercepts the three-brane in a four-dimensional rotating black hole. The geodesic equations and the asymptotics in this background are discussed.

Thin accretion disks around rotating black holes in 4D Einstein–Gauss–Bonnet gravity

European Physical Journal C: Particles and Fields, 2021
Recently, Kumar and Ghosh have derived Kerr-like rotating black hole solutions in the framework of four-dimensional Einstein–Gauss–Bonnet theory of gravity and investigated the black hole shadow. Using the steady-state Novikov–Thorne model, we study thin
