Semiclassical regularity of compact trapped regions: From dynamical horizons to inner extremality
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +1
In eternal black-hole spacetimes, inner horizons are Cauchy horizons and are generically unstable. For non-extremal inner horizons, this includes both the classical mass-inflation…
Timelike convergence condition in regular black-hole spacetimes with (anti-)de Sitter core
Johanna Borissova, Stefano Liberati, Matt Visser
The Hawking-Penrose (1970) singularity theorem weakens the causality assumption of global hyperbolicity used in the Penrose (1965) singularity theorem, at the expense of invoking t…
Violations of the null convergence condition in kinematical transitions between singular and regular black holes, horizonless compact objects, and bounces
Johanna Borissova, Stefano Liberati, Matt Visser
How do regular black holes evade the Penrose singularity theorem? Various models of stationary regular black holes globally satisfy the null convergence condition (NCC). At first g…
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…
Black Holes Inside and Out 2024: visions for the future of black hole physics
Niayesh Afshordi, Abhay Ashtekar, Enrico Barausse +27
The gravitational physics landscape is evolving rapidly, driven by our ability to study strong-field regions, in particular black holes. Black Holes Inside and Out gathered world e…
Fully extremal black holes: a black hole graveyard?
Francesco Di Filippo, Stefano Liberati, Matt Visser
While the standard point of view is that the ultimate endpoint of black hole evolution is determined by Hawking evaporation, there is a growing evidence that classical and semi-cla…
Mass inflation without Cauchy horizons
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +1
Mass inflation is a well established instability, conventionally associated to Cauchy horizons (which are also inner trapping horizons) of stationary geometries, leading to a diver…
Revisiting the semiclassical gravity scenario for gravitational collapse
C. Barcelo, S. Liberati, S. Sonego +1
The existence of extremely dark and compact astronomical bodies is by now a well established observational fact. On the other hand, classical General Relativity predicts the existe…
Quasi-particle creation by analogue black holes
Carlos Barcelo, Stefano Liberati, Sebastiano Sonego +1
We discuss the issue of quasi-particle production by ``analogue black holes'' with particular attention to the possibility of reproducing Hawking radiation in a laboratory. By cons…
Production and decay of evolving horizons
Alex B. Nielsen, Matt Visser
We consider a simple physical model for an evolving horizon that is strongly interacting with its environment, exchanging arbitrarily large quantities of matter with its environmen…
