Black holes and solution generating techniques
Adriano Viganò
Multi-black hole solutions play a relevant role both from the theoretical and the phenomenological point of view. In this Thesis, we construct some regular multi-black hole spaceti…
Black holes in a swirling universe
Marco Astorino, Riccardo Martelli, Adriano Viganò
We present a new solution in Einstein's General Relativity representing a Schwarzschild black hole immersed in a rotating universe. Such a solution is constructed analytically by m…
Bubbles of nothing in binary black holes and black rings, and viceversa
Marco Astorino, Roberto Emparan, Adriano Viganò
We argue that expanding bubbles of nothing are a widespread feature of systems of black holes with multiple or non-spherical horizons, appearing as a limit of regions that are narr…
AdS-Taub-NUT spacetimes and exact black bounces with scalar hair
José Barrientos, Adolfo Cisterna, Nicolás Mora +1
We present a new family of exact four-dimensional Taub-NUT spacetimes in Einstein- theory supplemented with a conformally coupled scalar field exhibiting a power-counting super-…
