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…
