Comment on "Regular evaporating black holes with stable cores"
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +2
Regular black holes are generically unstable because of the classical phenomenon that goes by the name of "mass inflation" which destabilizes the inner horizon. In a recent article…
A connection between regular black holes and horizonless ultracompact stars
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +1
We illustrate that regular black holes and horizonless stars, typically considered as quite distinct families of black hole mimickers, are intimately intertwined. We show that any…
Painleve-Gullstrand coordinates versus Kerr spacetime geometry
Matt Visser, Stefano Liberati
We discuss the tension between the possible existence of Painleve-Gullstrand coordinate systems versus the explicit geometrical features of the Kerr spacetime; a subject of interes…
Tidal heating in a Riemann-Cartan spacetime
Sudipta Hensh, Stefano Liberati, Vincenzo Vitagliano
We consider possible perturbations of the black hole event horizon induced by matter with spin, extending the derivation of the Hawking-Hartle formula (tidal heating) in the presen…
Frontiers of Quantum Gravity: shared challenges, converging directions
Jan de Boer, Bianca Dittrich, Astrid Eichhorn +10
Understanding the quantum nature of spacetime and gravity remains one of the most ambitious goals of theoretical physics. It promises to provide key new insights into fundamental p…
Stable Rotating Regular Black Holes
Edgardo Franzin, Stefano Liberati, Jacopo Mazza +1
We present a rotating regular black hole whose inner horizon has zero surface gravity for any value of the spin parameter, and is therefore stable against mass inflation. Our metri…
