Charging up regular black holes
Raúl Carballo-Rubio, Chiara Coviello, Vania Vellucci
We present a general construction of charged regular black holes as solutions of a generalization of the Einstein--Maxwell field equations in spherical symmetry in which the Einste…
From de Sitter to anti-de Sitter singularity regularization: Theory and phenomenology
Julio Arrechea, Stefano Liberati, Hooman Neshat +1
Recent investigations of vacuum polarization in extremely compact stars suggest that, in such regimes, the effective matter content of spacetime may acquire a vacuum-energy equatio…
Physical and Theoretical Challenges to Integrable Singularities
Julio Arrechea, Stefano Liberati, Hooman Neshat +1
Black hole spacetimes that exhibit integrable singularities have gained considerable interest as alternatives to both regular and singular black holes. Unlike most known regular bl…
Towards a Non-singular Paradigm of Black Hole Physics
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +18
The study of regular black holes and black hole mimickers as alternatives to standard black holes has recently gained significant attention, driven both by the need to extend gener…
Tidal response of regular black holes
Chiara Coviello, Luis Lehner, Vania Vellucci
In this work, we investigate the tidal deformability of regular black holes (RBHs). Employing different phenomenological models, we analyze their response to both test fields and g…
Whispers from the quantum core: the ringdown of semiclassical stars
Julio Arrechea, Stefano Liberati, Vania Vellucci
This investigation delves into the ringdown signals produced by semiclassical stars, which are ultra-compact, regular solutions of the Einstein equations incorporating stress-energ…
