Black hole inner horizon evaporation in semiclassical gravity
Carlos Barceló, Valentin Boyanov, Raúl Carballo-Rubio +1
In this work we analyse the backreaction of a quantum field on a spherically symmetric black hole geometry with an inner horizon, i.e. an internal boundary of the trapped region. W…
Vacuum semiclassical gravity does not leave space for safe singularities
Julio Arrechea, Carlos Barceló, Valentin Boyanov +1
General relativity predicts its own demise at singularities, but also appears to conveniently shield itself from the catastrophic consequences of such singularities, making them sa…
Asymptotic horizon formation, spacetime stretching and causality
Carlos Barceló, Valentin Boyanov, Raúl Carballo-Rubio +1
In this work we analyse asymptotically flat, spherically symmetric spacetimes in which an event horizon is present without any trapped surfaces. We identify two types of such space…
