Logarithmic corrections to black hole entropy from minimum-assumptions discretization
Pelayo V. Calzada, Ana Alonso-Serrano, Ernesto Contreras +1
We introduce here a general model, under agnostic and minimum assumptions, to uniquely find the entropy area law with a corresponding fixed logarithmic correction term. In this app…
Evading Cauchy horizon excision in scalarized regular black holes
Ernesto Contreras, Pedro Bargueño, Arthur G. Suvorov
Spontaneous scalarization provides a dynamical mechanism to evade the no-hair paradigm, but it has been argued to generically eliminate the Cauchy horizon in charged black holes. W…
Traversable ghost wormholes
Alberto Guilabert, Ernesto Fuenmayor, Pedro Bargueño +1
Ghost stars are compact configurations characterized by an arbitrarily small total mass. Such objects require regions of negative energy density -a condition typically regarded as…
General Framework for the Spontaneous Scalarization of Regular Black Holes
Ernesto Contreras, Mikaela Carrasco-Hidalgo, Pedro Bargueño +1
We investigate the spontaneous scalarization of generic, static, and spherically symmetric regular black holes supported by nonlinear electrodynamics. Starting from an arbitrary se…
Geodesic analysis and black hole shadows on a general non--extremal rotating black hole in five--dimensional gauged supergravity
E. Contreras, Á. Rincón, G. Panotopoulos +1
In this work, motivated by the fact that higher-dimensional theories predict the existence of black holes which differ from their four-dimensional counterpart, we analyse the geode…
Newman-Penrose scalars and black hole equations of state
F. D. Villalba, P. Bargueno, A. F. Vargas +1
In this work we explore the connections between Newman-Penrose scalars, including the Penrose-Rindler -curvature, with the equation of state of asymptotically Anti-de…
