PV: KERR BLACK HOLES WITH BOSONIC HAIR: THEORY AND PHENOMENOLOGY 
 ELENCO COMPLETO 

DATA: 03-05-2017

SEZIONE PAVIA
Over the last two years it has been found that new classes of asymptotically flat black hole solutions, regular on and outside the event horizon, bifurcating from the vacuum Kerr solution, exist in General Relativity, with simple matter contents that obey all energy conditions, namely Kerr black holes with scalar hair and Proca hair. In this talk, after briefly reviewing the observational evidence for black holes and their standard theoretical description, I will describe the general mechanism that allows the new solutions to exist, intimately connected to superradiance, how these solutions circumvent well known no-hair theorems and some of their phenomenology (shadows and x-ray spectra) which can be considerably distinct from that of Kerr.
