Superradiant instability of black holes immersed in a magnetic field
Abstract: Superradiance is a radiation enhancement process that involves dissipative systems. In General Relativity, black-hole superradiance is permitted by dissipation at the event horizon that allows for energy and angular momentum extraction from the vacuum, even at the classical level.
The Einstein-Yang-Mills anti-de Sitter menagerie
Abstract: Spherically symmetric black hole solutions of Einstein-Yang-Mills (EYM) theory have been studied for 25 years. In the past 15 years there has been a particular focus on EYM black holes in anti-de Sitter space (adS) since, unlike the situation in asymptotically flat space, in adS stable hairy EYM black holes exist.
Evidence for primordial gravitational waves from the BICEP2 experiment
Nonexistence of baryon number for black holes
Thickness corrections in topology changing brane - black hole systems
Abstract: The study of higher dimensional black holes, branes and their possible interactions is an active field of research in several different areas of modern theoretical physics. One interesting direction, which has been recently introduced by V.
