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…
