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 incorpo…

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…
