Geodesically complete black holes
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +1
The 1965 Penrose singularity theorem demonstrates the utterly inevitable and unavoidable formation of spacetime singularities under physically reasonable assumptions, and it remain…
Dark-Energy Instabilities induced by Gravitational Waves
Paolo Creminelli, Giovanni Tambalo, Filippo Vernizzi +1
We point out that dark-energy perturbations may become unstable in the presence of a gravitational wave of sufficiently large amplitude. We study this effect for the cubic Horndesk…
Testing Non-minimally Coupled BEC Dark Matter with Gravitational Waves
Dimitar Ivanov, Stefano Liberati
We study the phenomenology associated to non-minimally coupled dark matter. In particular, we consider the model where the non-minimal coupling arises from the formation of relativ…
The Spectra of Gravitational Atoms
Daniel Baumann, Horng Sheng Chia, John Stout +1
We compute the quasi-bound state spectra of ultralight scalar and vector fields around rotating black holes. These spectra are determined by the gravitational fine structure consta…
Opening the Pandora's box at the core of black holes
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +1
Unless the reality of spacetime singularities is assumed, astrophysical black holes cannot be identical to their mathematical counterparts obtained as solutions of the Einstein fie…
The information loss problem: an analogue gravity perspective
Stefano Liberati, Giovanni Tricella, Andrea Trombettoni
Analogue gravity can be used to reproduce the phenomenology of quantum field theory in curved spacetime and in particular phenomena such as cosmological particle creation and Hawki…
