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 کاملThe golden ratio and aesthetics
Mario Livio is a scientist and self−proclaimed "art fanatic" who owns many hundreds of art books. Recently, he combined his passions for science and art in two popular books, The Accelerating Universe, which appeared in 2000, and The Golden Ratio, reviewed in this issue of Plus. The former book discusses "beauty" as an essential ingredient in fundamental theories of the universe. The latter dis...
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 کاملThe Lovelock Black Holes
Lovelock theory is a natural extension of Einstein theory of gravity to higher dimensions, and it is of great interest in theoretical physics as it describes a wide class of models. In particular, it describes string theory inspired ultraviolet corrections to Einstein-Hilbert action, while admits the Einstein general relativiy and the so called Chern-Simons theories of gravity as particular cas...
متن کاملThe Brightest Black Holes
I suggest that there are two classes of ultraluminous X–ray sources (ULXs), corresponding to super–Eddington mass inflow in two situations: (a) thermal–timescale mass transfer in high–mass X–ray binaries, and (b) long–lasting transient outbursts in low–mass X–ray binaries. These two classes are exemplified by SS433 and microquasars like GRS 1915+105 respectively. The observed ULX population is ...
