Black objects in a five-dimensional swirling spacetime
Adriano Viganò
We construct a five-dimensional generalization of the swirling universe and embed in it the Myers-Perry black hole and the rotating black ring. We prove that both solutions are fre…
Kerr-Newman black hole in a Melvin-swirling universe
Andrea Di Pinto, Silke Klemm, Adriano Viganò
We present a new exact solution of Einstein-Maxwell field equations which represents a rotating black hole with both electric and magnetic charges immersed in a universe which itse…
Exact rotating wormholes via Ehlers transformations
Adolfo Cisterna, Keanu Müller, Konstantinos Pallikaris +1
In this paper, we construct exact rotating wormholes using Ehlers solution-generating technique. This is based on the Ernst description of four-dimensional, stationary, and axially…
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…
Many accelerating distorted black holes
Marco Astorino, Adriano Viganò
An analytical metric of four-dimensional General Relativity, representing an array of collinear and accelerating black holes, is constructed with the inverse scattering method. The…
Charged and rotating multi-black holes in an external gravitational field
Marco Astorino, Adriano Viganò
We construct analytical and regular solutions in four-dimensional General Relativity which represent multi-black hole systems immersed in external gravitational field configuration…
Binary black hole system at equilibrium
Marco Astorino, Adriano Viganò
An exact and analytical solution of four dimensional vacuum General Relativity representing a system of two static black holes at equilibrium is presented. The metric is completely…
Analogue Hawking Effect: BEC and Surface Waves
F. Belgiorno, S. L. Cacciatori, A. Farahat +1
We take into account two further physical models which play an utmost importance in the framework of Analogue Gravity. We first consider Bose--Einstein condensates (BEC) and then s…
Analogue Hawking Effect: a master equation
F. Belgiorno, S. L. Cacciatori, A. Viganò
We consider further on the problem of the analogue Hawking radiation. We propose a fourth order ordinary differential equation, which allows to discuss the problem of Hawking radia…
Electromagnetic self-force in curved spacetime: New insights from the Janis-Newman algorithm
Matteo Broccoli, Adriano Viganò
We present an original approach to compute the electromagnetic self-force acting on a static charge in Kerr spacetime. Our approach is based on an improved version of the Janis-New…
