Thermal and optical signatures of a magnetic AdS black hole in dark matter and quintessence
Mohsen Fathi, Marco Olivares, Carlos E. Romero-Figueroa +1
We study a static magnetic anti-de Sitter black hole surrounded by perfect-fluid dark matter and quintessence. We follow the geometry from the horizon to the observer. We first exa…
Inverse Reconstruction of Causal Nonlinear Electrodynamics: Functional Families, Spectral Constraints, and Single-Horizon Black Holes
Ariel Guzmán, Mohsen Fathi, J. R. Villanueva
Nonlinear electrodynamics (NLED) admits many causal theories, so causality alone does not provide a unique selection principle. We formulate an inverse construction in which consti…
Dark-Sector Effects on the Phase Structure of Nonlinear Magnetic AdS Black Holes
Carlos E. Romero-Figueroa, J. R. Villanueva
We investigate the effects of perfect fluid dark matter (PFDM) and a dark-energy field on the phase structure of a nonlinear magnetically charged Anti--de Sitter (NLMC--AdS) black…
A causal magnetic black hole with finite self-energy
Mohsen Fathi, Ariel Guzmán, J. R. Villanueva
We construct a nonlinear electrodynamics (NLED) model for a static magnetic black hole. Rather than imposing a regular center, we require a Maxwell weak-field limit, finite magneti…
