Quasi-normal modes and microscopic description of 2D black holes

Mariano Cadoni, Mauro Oi, Andrea Pierfrancesco Sanna

We investigate the possibility of using quasi-normal modes (QNMs) to probe the microscopic structure of two-dimensional (2D) anti-de Sitter (AdS) dilatonic black holes. We firs…

Quasi-normal modes and Microscopic Structure of the Schwarzschild Black Hole

Mariano Cadoni, Mauro Oi, Andrea P. Sanna

Maggiore observed that, in the high-damping regime, the quasi-normal modes spectrum for the Schwarzschild black hole resembles that of a quantum harmonic oscillator. Motivated by t…

Dyonic black holes in nonlinear electrodynamic from Kaluza-Klein theory with a Gauss-Bonnet term

S. Mignemi

Five-dimensional Kaluza-Klein theory with an Einstein-Gauss-Bonnet Lagrangian induces nonlinear corrections to the four-dimensional Maxwell equations, which however remain second o…

Conformalons: a new class of black hole mimickers

Leonardo Modesto, Ali Akil, Cosimo Bambi

In any conformally invariant gravitational theory, the space of exact solutions is greatly enlarged. Therefore, we cannot exclude the Weyl's conformal invariance to be spontaneousl…

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…

Unified description of galactic dynamics and the cosmological constant

Mariano Cadoni, Andrea P. Sanna

We explore the phenomenology of a two-fluid cosmological model, where the field equations of general relativity (GR) are sourced by baryonic and cold dark matter. We find that the…
