Description
This talk deals with AdS black holes arising as solutions of
four dimensional supergravity admitting an embedding in
M-theory. Supersymmetric AdS4 black holes with spherical
horizon were discovered quite recently and have lately
attracted some attention, given that their entropy was
successfully reproduced via the computation of the twisted
Witten index in ABJM theory. After reviewing recent progress
in the analysis of supersymmetric and non supersymmetric
configurations, I will discuss some ongoing work on a class
of new solutions arising from M-theory on 7d Sasaki-Einstein
coset manifolds. Such thermal black holes are characterized
by charged scalars and massive vector fields. The analysis
of the stability of probes in such a background gives
insight on the possible existence of stable of multi-center
black holes in anti-de Sitter, relevant for the holographic
description of the glass phase transition.
