Challenging the Weak Cosmic Censorship with Phantom Fields
Giovanni Caridi, Fabrizio Corelli, Paolo Pani
Penrose's weak cosmic censorship conjecture asserts that spacetime singularities produced by gravitational collapse are generically hidden behind event horizons, thus preventing th…
Gravity with higher-curvature terms and second-order field equations: meets Gauss-Bonnet
Fabrizio Corelli, Paolo Pani, Andrea P. Sanna
General Relativity is expected to break down in the high-curvature regime. Beyond an effective field theory treatment with higher-order operators, it is important to identify consi…
Black hole spectroscopy and nonlinear echoes in Einstein-Maxwell-scalar theory
Marco Melis, Fabrizio Corelli, Robin Croft +1
In the context of Einstein-Maxwell-scalar theory with a nonminimal coupling between the electromagnetic and scalar field, we study linear (non)radial perturbations and nonlinear ra…
Nonlinear photon-plasma interaction and the black hole superradiant instability
Enrico Cannizzaro, Fabrizio Corelli, Paolo Pani
Electromagnetic field confinement due to plasma near accreting black holes can trigger superradiant instabilities at the linear level, limiting the spin of black holes and providin…
Nonperturbative gedanken experiments in Einstein-dilaton-Gauss-Bonnet gravity: nonlinear transitions and tests of the cosmic censorship beyond General Relativity
Fabrizio Corelli, Marina De Amicis, Taishi Ikeda +1
As the only gravity theory with quadratic curvature terms and second-order field equations, Einstein-dilaton-Gauss-Bonnet gravity is a natural testbed to probe the high-curvature r…
What is the fate of Hawking evaporation in gravity theories with higher curvature terms?
Fabrizio Corelli, Marina De Amicis, Taishi Ikeda +1
During the final stages of black hole evaporation, ultraviolet deviations from General Relativity eventually become dramatic, potentially affecting the end-state. We explore this p…
Instability of Schwarzschild Black Holes in Einstein-scalar-Gauss-Bonnet Gravity: Perturbative Approach and Time-Domain Analysis
Fabrizio Corelli
We study the instability of Schwarzschild black holes and the appearance of scalarized solutions in Einstein-scalar-Gauss-Bonnet gravity performing a time-domain analysis in a pert…
Challenging the cosmic censorship in Einstein-Maxwell-scalar theory with numerically simulated gedankenexperiments
Fabrizio Corelli, Taishi Ikeda, Paolo Pani
We perform extensive nonlinear numerical simulations of the spherical collapse of (charged) wavepackets onto a charged black hole within Einstein-Maxwell theory and in Einstein-Max…
