Geodesically complete black holes
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +1
The 1965 Penrose singularity theorem demonstrates the utterly inevitable and unavoidable formation of spacetime singularities under physically reasonable assumptions, and it remain…
Schwarzschild geometry counterpart in semiclassical gravity
Julio Arrechea, Carlos Barceló, Raúl Carballo-Rubio +1
We investigate the effects of vacuum polarization on vacuum static spherically-symmetric spacetimes. We start from the Polyakov approximation to the renormalized stress-energy tens…
Opening the Pandora's box at the core of black holes
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +1
Unless the reality of spacetime singularities is assumed, astrophysical black holes cannot be identical to their mathematical counterparts obtained as solutions of the Einstein fie…
Amplitudes, Gravity and Classical Discontinuities
Daniel J. Burger, Raul Carballo-Rubio, Nathan Moynihan +2
On-shell methods have revitalized interest in scattering amplitudes which have, in turn, shed some much needed light on the structure of quantum field theories. These developments…
Semiclassical gravity effects near horizon formation
Carlos Barceló, Valentin Boyanov, Raúl Carballo-Rubio +1
We study the magnitude of semiclassical gravity effects near the formation of a black-hole horizon in spherically-symmetric spacetimes. As a probe for these effects we use a quanti…
Generalized no-hair theorems without horizons
Carlos Barceló, Raúl Carballo-Rubio, Stefano Liberati
The simplicity of black holes, as characterized by no-hair theorems, is one of the most important mathematical results in the framework of general relativity. Are these theorems un…
