A study on matter accretion onto charged black hole solution in metric-affine gravity
G. Mustafa, A. Ditta, Faisal Javed +3
This study deals with astrophysical accretion onto the charged black hole solution, which is sourced by the dilation, spin, and shear charge of matter in metric affine gravity. The…
Joule-Thomson expansion and tidal force effects of AdS black holes surrounded by Chaplygin dark fluid
Dhruv Arora, Muhammad Yasir, Himanshu Chaudhary +4
This study examines a recently hypothesized black hole. We study the Joule-Thomson coefficient, the inversion temperature and also the isenthalpic curves in the plane. A…
Weak gravitational lensing and shadow of a GUP-modified Schwarzschild black hole in the presence of plasma
Husanboy Hoshimov, Odil Yunusov, Farruh Atamurotov +2
In this work, we have studied weak gravitational lensing effect around black hole and determine shadow radius in GUP-corrected-Schwarzschild spacetime (S-GUP) in presence of plasma…
Circular orbits and accretion disk around AdS black holes surrounded by dark fluid with Chaplygin-like equation of state
G. Mustafa, S. K. Maurya, A. Ditta +2
In the present work we study the geodesic motion and accretion process of a test particle near an Anti-de Sitter (ADS) BH surrounded by a dark fluid with a Chaplygin-like equation.…
Strong Gravitational Lensing by Sgr A* and M87* Black Holes embedded in Dark Matter Halo exhibiting string cloud and quintessential field
Niyaz Uddin Molla, Himanshu Chaudhary, Dhruv Arora +3
We investigate the strong gravitational lensing phenomena caused by a black hole with a dark matter halo. In this study, we examine strong gravitational lensing with two significan…
Exploring Tidal Force Effects and Shadow Constraints for Schwarzschild-like Black Hole in Starobinsky-Bel-Robinson Gravity
Dhruv Arora, Niyaz Uddin Molla, Himanshu Chaudhary +3
The current manuscript deals with the tidal force effects, geodesic deviation, and shadow constraints of the Schwarzschild-like black hole theorised in Starobinsky-Bel-Robinson gra…
Addressing the Tension using Late-Time Observational Measurements in a Novel deceleration Parametrization
Himanshu Chaudhary, Ujjal Debnath, G. Mustafa +2
This paper introduces a novel cosmological model aimed at probing the accelerated expansion of the late Universe through a unique parametrization of the deceleration parameter. We…
Probing Geometric Proca in Metric-Palatini Gravity with Black Hole Shadow and Photon Motion
Elham Ghorani, Beyhan Puliçe, Farruh Atamurotov +3
Extended metric-Palatini gravity, quadratic in the antisymmetric part of the affine curvature, is known to lead to the general relativity plus a geometric Proca field. The geometri…
Testing the Metric-Affine Gravity Using Particle Dynamics and Photon Motion
Allah Ditta, Xia Tiecheng, Saadia Mumtaz +3
This work mainly focuses to unveil the optical features of a black hole. For this objective, we utilize the metric-affine black hole geometry with the inclusion of dilation, spin,…
Constraining study of circular orbits and accretion disk around nonlinear electrodynamics black hole
A. Ditta, G. Mustafa, G. Abbas +2
The very latest observation of supermassive black hole (BH) by the Event Horizon Telescope (EHT) provides the accretion onto BHs is an interesting study in the theory of grav…
