Scalar stars and lumps with (A)dS core
Mariano Cadoni, Mauro Oi, Mirko Pitzalis +1
We explore the possibility of embedding regular compact objects with (anti) de Sitter ((A)dS) core as solutions of Einstein's gravity minimally coupled to a real scalar field. We c…
Are nonsingular black holes with super-Planckian hair ruled out by S2 star data?
M. Cadoni, M. De Laurentis, I. De Martino +3
We propose a novel nonsingular black-hole spacetime representing a strong deformation of the Schwarzschild solution with mass by an additional hair , which may be hierarc…
Semiclassical spacetimes at super-Planckian scales from delocalized sources
Ali Akil, Mariano Cadoni, Leonardo Modesto +2
We derive the gravitational field and the spacetime metric generated by sources in quantum superposition of different locations. We start by working in a Newtonian approximation, i…
Atmospheric Newtonian noise modeling for third-generation gravitational wave detectors
Davide Brundu, Mariano Cadoni, Mauro Oi +2
The sensitivity and the frequency bandwidth of third-generation gravitational-wave (GW) detectors are such that the Newtonian noise (NN) signals produced by atmospheric turbulence…
Effective models of non-singular quantum black holes
Mariano Cadoni, Mauro Oi, Andrea Pierfrancesco Sanna
We investigate how the resolution of the singularity problem for the Schwarzschild BH could be related to the presence of quantum gravity effects at horizon scales. Motivated by th…
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…
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…
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…
