Hawking-like radiation from evolving black holes and compact horizonless objects
Hawking-like radiation evolving black holes compact horizonless objects
2010/12/27
Usually, Hawking radiation is derived assuming (i) that a future eternal event horizon forms, and (ii) that the subsequent exterior geometry is static. However, one may be interested in either conside...
A local characterisation for static charged black holes
local characterisation static charged black holes
2010/12/20
We obtain a purely local characterisation that singles out the Majumdar-Papapetrou class, the near-horizon Bertotti-Robinson geometry and the Reissner-Nordstr¨om exterior solution, together with its p...
Universal Area Product Formulae for Rotating and Charged Black Holes in Four and Higher Dimensions
Product Formulae Rotating Charged Black Holes
2010/12/22
We present explicit results for the product of all horizon areas for general rotating multi-charge black holes, both in asymptotically flat and asymptotically anti-de Sitter spacetimes in four and hig...
