Spherical Accretion onto Konoplya Zhidenko Black Holes: Sonic Point Analysis and Fluid Dynamics
M H Waheed, M Z A Moughal
We investigate the spherical accretion onto a static Konoplya Zhidenko black hole and examine how the deformation of the spacetime affects the dynamics of the accreting matter. By…
Energy Extraction from Rotating Black Hole with Quintessential Energy through the Penrose Process
K. Q. Abbasi, F. L. Carneiro, M. Z. A. Moughal
We investigate the geometry, dynamics, and collision mechanisms in the ergoregion of KerrNewman-AdS black hole influenced by quintessential energy. Particle splittings within the e…
Accretion with Back-Reaction onto Cylindrically Symmetric Black Hole with Energy Conditions Analysis
Muhammad Zubair Ali Moughal, Kamran Qadir Abbasi
This paper is devoted to study back-reaction effects from matter accretion onto a cylindrically symmetric black hole using a perturbative scheme, focusing on cases where accretion…
Universal thermodynamic topological classes of black holes in perfect fluid dark matter background
Muhammad Rizwan, Mubasher Jamil, M. Z. A. Moughal
In this paper, we study the universal thermodynamic topological classes of a family of black holes in a perfect fluid dark matter (PFDM) background. Recent research on black hole t…
