Hairy Kiselev black hole with quintessential matter: themodynamic properties, sparsity of Hawking radiation, and greybody factors
Faizuddin Ahmed, Fernando M. Belchior, Allan R. P. Moreira +1
In this work, we investigate the thermodynamic properties, Hawking-radiation sparsity, and greybody-factor bounds of a hairy Kiselev black hole surrounded by a quintessential fluid…
Quantum Oppenheimer-Snyder Black Holes with a Cloud of Strings Surrounded by Perfect Fluid Dark Matter
Faizuddin Ahmed, Allan R. P. Moreira, Abdelmalek Bouzenada
In this study, we examine quantum Oppenheimer-Snyder black holes (BHs) embedded within a cloud of strings and immersed in perfect fluid dark matter. Also, beginning with the underl…
Dymnikova Black Hole Immersed in Perfect Fluid Dark Matter and a Cloud of Strings: Hawking Temperature, Dynamics and QPOs Analysis
Faizuddin Ahmed, Sardor Murodov, Bekzod Rahmatov +1
The Dymnikova black hole represents a regular spacetime solution interpolating between a de Sitter core and an asymptotically Schwarzschild geometry. In this work, we investigate a…
Static AdS Black Holes Surrounded by Strings and Quintessence-like Field within Rastall Gravity Framework
Allan. R. P. Moreira, Faizuddin Ahmed, Abdelmalek Bouzenada
In this work, we tested the physical properties of Rastall black holes in the presence of string clouds and quintessence. The modified spacetime geometry arising from the Rastall f…
AdS Black Hole Solution with a Dark Matter Halo Surrounded by a Cloud of Strings
Faizuddin Ahmed, Abdelmalek Bouzenada, Edilberto O. Silva
We derive and analyze a Schwarzschild-like Anti-de Sitter (AdS) black hole (BH) obtained as a static, spherically symmetric solution of Einstein's equations sourced by a cloud of s…
Dynamics of test particles, QPOs and thermodynamics of charged Euler-Heisenberg AdS black holes with a cloud of strings and dark matter
Faizuddin Ahmed, Ahmad Al-Badawi, İzzet Sakallı
We investigate the geodesic motion of test particles around a charged Euler-Heisenberg Anti-de Sitter black hole (CEH-AdS-BH) with a cloud of strings (CoS) and surrounded by perfec…
