Hawking Temperature, Sparsity and Energy Emission Rate of Regular Black Holes Supported by Primordial Dark Matter
Faizuddin Ahmed, Ahmad Al-Badawi, Edilberto O. Silva
In this paper, we investigate the thermodynamic and radiative properties of a regular black hole sourced by primordial dark matter (PDM), modeled effectively through a Dirac--Born-…
Astrophysical Signatures of Einstein-Skyrme Anti-de Sitter Black Holes: Epicyclic Frequencies and QPO Constraints
Faizuddin Ahmed, Ahmad Al-Badawi, İzzet Sakallı
We study the geodesic motion and epicyclic oscillations of massive test particles around a static, spherically symmetric black hole (BH) solution of the Einstein--Skyrme (ES) theor…
Spin-(, , ) Field Perturbations, Quasinormal Modes, Overtones, Greybody Factors and Strong Cosmic Censorship of Einstein-Skyrme Black Holes
Faizuddin Ahmed, Ahmad Al-Badawi, İzzet Sakallı
We carry out a multi-spin perturbation-theory study of the four-dimensional Einstein-Skyrme (ES) anti-de Sitter (AdS) black hole (BH), whose lapse inhe…
Shadow, Sparsity of Radiation and Energy Emission Rate in Skyrmion Black Holes
Faizuddin Ahmed, Ahmad Al-Badawi, İzzet Sakallı
We examine several observable optical properties of a Skyrmion black hole (BH), focusing on the photon sphere, BH shadow, and photon trajectories. The Skyrme term, along with other…
Renormalization-group improved Schwarzschild black hole: shadow, ringdown, and strong cosmic censorship
Ahmad Al-Badawi, Faizuddin Ahmed, İzzet Sakallı
A renormalization-group (RG) improved Schwarzschild-like black hole (BH) is studied here, with a lapse that interpolates between a classical Schwarzschild exterior and a quantum-sm…
Plummer Dark Matter Black Hole with Topological Defects: Shadow, Greybody Factors, Quasinormal Modes, and Thermodynamics
Ahmad Al-Badawi, Faizuddin Ahmed, İzzet Sakallı
We construct a static, spherically symmetric black hole (BH) solution embedded in a cored Plummer dark matter (DM) halo and a Letelier cloud of strings (CoS). Starting from the Plu…
