Constraining Cosmological Parameters From Statistical Superluminal Effects Without a Distance Ladder

Hichem Guergouri, Omar Nemoul, Jamal Mimouni

We employ a statistical approach to study apparent superluminal motion of luminous sources in an expanding flat Friedmann--Lemaître--Robertson--Walker universe, explicitly incorpor…

Thermodynamics, Phase Transitions, and Geodesic Structure of F(R)-Phantom Banados-Teitelboim-Zanelli (BTZ) Black Holes

Behzad Eslam Panah, Bilel Hamil, Manuel E. Rodrigues

This paper investigates phantom BTZ black holes within the high-curvature gravity theory framework, specifically using a special case of power-Maxwell theory, which functions as a…

Born-Infeld AdS Black Holes Surrounded by Perfect Fluid Dark Matter

Behzad Eslam Panah, Bilel Hamil, Manuel E. Rodrigues

We obtain exact charged AdS black hole solutions in Einstein Lambda gravity including the effects of Born Infeld nonlinear electrodynamics and Perfect Fluid Dark Matter. The influe…

Topological Mod(A)Max AdS black holes

B. Eslam Panah, B. Hamil, Manuel E. Rodrigues

In this work, we construct new classes of topological black hole solutions in anti-de Sitter (AdS) spacetime using a novel model of nonlinear electrodynamics called Modification Ma…

Lensing in matched exterior and interior Kottler solutions

Mourad Guenouche

We analyze gravitational lensing in a matched Kottler spacetime with cosmological constant , where a uniform-density fluid sphere described by the interior Kottler solution is s…

Deflection of light and time delay in hyperbolic Einstein-Straus--de Sitter solution

Mourad Guenouche

We analyze strong gravitational lensing by a spherically symmetric mass distribution within the Einstein-Straus-de Sitter framework in a spatially open Universe with negative curva…
