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…
Scalar Field Dynamics in Non-Minimally Coupled Theories via the Noether Symmetry and the Eisenhart-Duval Lift
Ahmadfikri Talek, Narakorn Kaewkhao, Watcharakorn Srikom +2
This study investigates the dynamics of a non-minimally coupled (NMC) scalar field in modified gravity, employing the Noether gauge symmetry (NGS) approach to systematically derive…
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…
