Thermodynamics, Shadow, and Quasinormal Modes of AdS Ayón--Beato--García Massive Black Hole

Dharm Veer Singh, Sudhaker Upadhyay, Amit Kumar +3

We investigate the thermodynamics, photon sphere, and dynamical stability of an AdS Ayón--Beato--García (ABG) massive black hole with graviton mass and magnetic charge. The Gibbs f…

Refined Thermodynamic Analysis of Perfect Fluid Dark Matter Black Holes in a Phantom Background

Jyotish Kumar, Sudhaker Upadhyay, Himanshu Kumar Sudhanshu +2

In this study, we examine the thermodynamics of black holes immersed in perfect fluid dark matter (PFDM) by employing the Misner-Sharp energy framework. We extend the analysis to i…

Nonminimally Coupled Quintessence with Double Exponential Potential: Observational Evidence Against Big Crunch Singularity

Yerlan Myrzakulov, Saddam Hussain, Mohd Shahalam

We investigate a class of scalar field dark energy models non-minimally coupled to gravity, characterized by a double exponential potential and parameterized coupling . We study…
