Optical Signatures of Sgr A* and M87* with Dark Matter Halos
Noraiz Tahir, Muhammad Ali Paracha, Mubasher Jamil
The event horizon telescope (EHT) has opened a new window onto the strong-field regime by imaging the shadows of the supermassive black holes (SMBHs) Sgr A* and M87*. These observa…
Chaotic imprints of dark matter in extreme mass-ratio inspirals
Mustapha Azreg-Aïnou, Mustapha Azreg-Aïnou, Mubasher Jamil +1
Extreme mass-ratio inspirals (EMRIs) are among the most powerful probes of strong-field gravity and of the environments surrounding supermassive compact objects. Motivated by the e…
Shadow of F(R)-EH Black Hole and Constraints from EHT Observations
Khadije Jafarzade, Saira Yasmin, Mubasher Jamil
This work investigates the optical properties of a static, spherically symmetric, electrically charged black hole in f(R) gravity coupled to Euler-Heisenberg(EH) nonlinear electrod…
Probing the nature of Einstein nonlinear Maxwell Yukawa black hole through gravitational wave forms from periodic orbits and quasiperiodic oscillations
Oreeda Shabbir, Abubakir Shermatov, Bushra Majeed +3
In this work, we study gravitational wave emission from periodic orbits of test particles, analyze quasi periodic oscillations, and constrain the parameters of the static, spherica…
Shadow geometry of Kerr MOG naked singularity and analysis of accretion disk luminosity
Saira Yasmin, Mubasher Jamil
Naked singularities are hypothetical astrophysical entities featuring gravitational singularities without event horizons. In this study, we analyze the shadow properties of Kerr Mo…
Gravitational wave radiation from periodic orbits and quasi-periodic oscillations in Einstein non-linear Maxwell-Yukawa black hole
Tehreem Zahra, Oreeda Shabbir, Bushra Majeed +3
In this article, we investigate the orbital dynamics and quasi-periodic oscillations (QPOs) surrounding a static, spherically symmetric geometry of an Einstein-nonlinear Maxwell-Yu…
