Toroidal black holes in four dimensions
Carlos Barceló, Gerardo García-Moreno, Alejandro Jiménez Cano
From a purely geometric (kinematic) perspective, black holes in four dimensional spacetimes can have event horizons with arbitrary topologies. It is only when energy conditions are…
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…
Beyond Buchdahl's limit: bilayered stars and thin-shell configurations
Julio Arrechea, Carlos Barceló, Gerardo García-Moreno +1
One of the theoretical motivations behind the belief that black holes as described by general relativity exist in nature is that it is hard to find matter configurations that mimic…
No-hair and almost-no-hair results for static axisymmetric black holes and ultracompact objects in astrophysical environments
Carlos Barceló, Raúl Carballo-Rubio, Luis J. Garay +1
No-hair theorems are uniqueness results constraining the form of the metric of black holes in general relativity. These theorems are typically formulated under idealized assumption…
