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…
