Weak deflection angle of black-bounce traversable wormholes using Gauss-Bonnet theorem in the dark matter medium
Ali Övgün
In this paper, we first use the optical metrics of black-bounce traversable wormholes to calculate the Gaussian curvature. Then we use the Gauss-Bonnet theorem to obtain the weak d…
Weak gravitational lensing by Einstein-non-linear-Maxwell-Yukawa black hole
Wajiha Javed, Muhammad Bilal Khadim, Ali Övgün
In this article, we analyze the weak gravitational lensing in the context of Einstein-non-linear Maxwell-Yukawa black hole. To this desire, we derive the deflection angle of light…
Weak Deflection angle of some classes of non-linear electrodynamics black holes via Gauss-Bonnet Theorem
H. El Moumni, K. Masmar, Ali Övgün
In this paper, we study the gravitational lensing by some black hole classes within the non-linear electrodynamics in weak field limits. First, we calculate an optical geometry of…
Effect of the quintessential dark energy on weak deflection angle by Kerr-Newmann Black hole
W. Javed, J. Abbas, A. Övgün
In this work, we study the weak gravitational lensing in the background of Kerr-Newman black hole with quintessential dark energy. Initially, we compute the deflection angle of lig…
Weak Gravitational lensing by Bocharova-Bronnikov-Melnikov-Bekenstein black holes using Gauss-bonnet theorem
Wajiha Javed, Muhammad Bilal Khadim, Ali Övgün
In this article, we demonstrate the weak gravitational lensing in the context of Bocharova-Bronnikov-Melnikov-Bekenstein (BBMB) black hole. To this desire, we derive the deflection…
Circular orbit of a particle and weak gravitational lensing
Zonghai Li, Guodong Zhang, Ali Övgün
The purpose of this paper is twofold. First, we introduce a geometric approach to study the circular orbit of a particle in static and spherically symmetric spacetime based on Jaco…
