Alessandra Gnecchi: In this talk I will underline aspects of gauged Supergravity solutions in four dimensional Anti de Sitter and flat space, as Supergravity theories with gauging admit flat as well as curved space vacua. I will present recent studies on black holes in Anti de Sitter, both in the supersymmetric as well as non-extremal case, with particular interest in their string-theory origin and holographic interpretation. I will then consider flat-gaugings, for which the theory still possesses a Minkowski vacuum, and explain how they affect black hole physics, in particular their microscopic interpretation, according to the Rholography construction. 20 Gennaio 2016.
