Superradiance in deformed Kerr black holes
Mauro Oi, Edgardo Franzin, Stefano Liberati
Ongoing observations in the strong-field regime are in optimal agreement with general relativity, although current errors still leave room for small deviations from Einstein's theo…
Charged black-bounce spacetimes
Edgardo Franzin, Stefano Liberati, Jacopo Mazza +2
Given the recent development of rotating black-bounce-Kerr spacetimes, for both theoretical and observational purposes it becomes interesting to see whether it might be possible to…
Superradiance in Kerr-like black holes
Edgardo Franzin, Stefano Liberati, Mauro Oi
Recent strong-field regime tests of gravity are so far in agreement with general relativity. In particular, astrophysical black holes appear all to be consistent with the Kerr spac…
Stationary spacetimes with time-dependent real scalar fields
Edgardo Franzin, Ivica Smolić
In 1981 Wyman classified the solutions of the Einstein--Klein--Gordon equations with static spherically symmetric spacetime metric and vanishing scalar potential. For one of these…
Tidal Love Numbers of Kerr Black Holes
Alexandre Le Tiec, Marc Casals, Edgardo Franzin
The open question of whether a Kerr black hole can become tidally deformed or not has profound implications for fundamental physics and gravitational-wave astronomy. We consider a…
Sine-Gordon solitonic scalar stars and black holes
Edgardo Franzin, Mariano Cadoni, Matteo Tuveri
We study exact, analytic, static, spherically symmetric, four-dimensional solutions of minimally coupled Einstein-scalar gravity, sourced by a scalar field whose profile has the fo…
