Classical instability of Kerr-AdS black holes and the issue of final state

Vitor Cardoso, Oscar J. C. Dias, Shijun Yoshida

It is now established that small Kerr-Anti-de Sitter (Kerr-AdS) black holes are unstable against scalar perturbations, via superradiant amplification mechanism. We show that small…

Perturbations and absorption cross-section of infinite-radius black rings

Vitor Cardoso, Oscar J. C. Dias, Shijun Yoshida

We study scalar field perturbations on the background of non-supersymmetric black rings and of supersymmetric black rings. In the infinite-radius limit of these geometries, we are…

Superradiant instabilities of rotating black branes and strings

Vitor Cardoso, Shijun Yoshida

Black branes and strings are generally unstable against a certain sector of gravitational perturbations. This is known as the Gregory-Laflamme instability. It has been recently arg…

The Fate of a Five-Dimensional Rotating Black Hole via Hawking Radiation

Hidefumi Nomura, Shijun Yoshida, Makoto Tanabe +1

We study the evolution of a five-dimensional rotating black hole emitting scalar field radiation via the Hawking process for arbitrary initial values of the two rotation parameters…

Scalar perturbations of higher dimensional rotating and ultra-spinning black holes

Vitor Cardoso, George Siopsis, Shijun Yoshida

We investigate the stability of higher dimensional rotating black holes against scalar perturbations. In particular, we make a thorough numerical and analytical analysis of six-dim…

The black hole bomb and superradiant instabilities

Vitor Cardoso, Oscar J. C. Dias, Jose' P. S. Lemos +1

A wave impinging on a Kerr black hole can be amplified as it scatters off the hole if certain conditions are satisfied giving rise to superradiant scattering. By placing a mirror a…
