Dark Matter Imprints on Black Hole Shadows and Chaotic Dynamics: A Comparative Study of Halo Profiles around Sgr A and M87
Ali Naqi, Mubasher Jamil, Noraiz Tahir +1
The gravitational influence of dark matter (DM) halos on the strong-field regime around supermassive black holes (SMBHs) remains largely unexplored. In the present work, we try to…
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, Mubasher Jamil, Emmanuel N. Saridakis
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

In this paper, we consider the Buchdahl-inspired spacetime metric and investigate its aspects using the quasiperiodic oscillations and the accretion disk due to the accreting matte…
Spin precession frequencies of a test gyroscope around a naked singularity and quasi-periodic oscillations
Tehreem Zahra, Mubasher Jamil, Mustapha Azreg-Aïnou
Various studies show that the gravitational collapse of inhomogeneous matter clouds leads to naked singularity formation. We investigate here the spin precession frequency of a tes…
