Abstract (italian or english)

We present a new family of asymptotically locally AdS5 squashed supersymmetric black hole solutions of Fayet–Iliopoulos gauged N = 2, D = 5 supergravity with two vector multiplets that have a natural uplift to type IIB supergravity. Our new family of black holes is characterized by three parameters, of which two control the horizon geometry while the latter regulates the squashing at the boundary. We evaluate the main physical properties of the family of solutions using holographic renormalization and find that the entropy is independent on the squashing and it is reproduced by using the angular momentum and the Page charges. In previously known solutions Page and holographic charges are equal, due to the vanishing of the Chern–Simons term that here, instead, is relevant. This result suggests that for asymptotically locally AdS5 solutions we should refer to the Page charges to describe the thermodynamics of the system.
