Dirty Black Holes and Hairy Black Holes.
An approach based on considerations of the non-classical energy momentum tensor outside the event horizon of a black hole provides additional physical insight into the nature of discrete quantum hair on black holes and its effect on black hole temperature. Our analysis both extends previous work based on the Euclidean action techniques, and corrects an omission in that work. We also raise sever...
متن کاملCaged Black Holes: Black Holes in Compactified Spacetimes I – Theory
In backgrounds with compact dimensions there may exist several phases for black objects including the black-hole and the black-string, and the phase transition between them raises puzzles and touches fundamental issues such as topology change, uniqueness and cosmic censorship. No analytic solution is known for the black hole, and moreover, one can expect approximate solutions only for very smal...
متن کاملBlack Holes in Astrophysics
This article reviews the current status of black hole astrophysics, focusing on topics of interest to a physics audience. Astronomers have discovered dozens of compact objects with masses greater than 3M⊙, the likely maximum mass of a neutron star. These objects are identified as black hole candidates. Some of the candidates have masses ∼ 5− 20M⊙ and are found in X-ray binaries, while the rest ...
متن کاملBlack Holes in Supergravity
A brief review is given of the use of duality symmetries to form orbits of supergravity black-hole solutions and their relation to extremal (i.e. BPS) solutions at the limits of such orbits. An important technique in this analysis uses a timelike dimensional reduction and exchanges the stationary black-hole problem for a nonlinear sigma-model problem. Families of BPS solutions are characterized...
متن کاملCharged black holes from near extremal black holes
We recover the properties of a wide class of far from extremal charged black branes from properties of near extremal black branes, generalizing the results of Danielsson, Guijosa and Kruczenski.
