Deriving Weak Deflection Angle by Black Holes or Wormholes using Gauss-Bonnet Theorem
Yashmitha Kumaran, Ali Övgün
In this review, various researches on finding the bending angle of light deflected by a massive gravitating object which regard the Gauss-Bonnet theorem as the premise have been re…
Nonlinear electrodynamics effects on the black hole shadow, deflection angle, quasinormal modes and greybody factors
Mert Okyay, Ali Övgün
In this paper, we discuss the effects of nonlinear electrodynamics (NED) on non-rotating black holes, parametrized by the field coupling parameter and magnetic charge parameter…
Black hole with confining electric potential in scalar-tensor description of regularized 4-dimensional Einstein-Gauss-Bonnet gravity
A. Övgün
In this paper, we analytically present an exact confining charged black hole solution to the scalar-tensor description of regularized 4-dimensional Einstein-Gauss-Bonnet gravity (4…
Weak deflection angle by asymptotically flat black holes in Horndeski theory using Gauss-Bonnet theorem
Wajiha Javed, Jameela Abbas, Yashmitha Kumaran +1
The principal objective of this project is to investigate the gravitational lensing by asymptotically flat black holes in the framework of Horndeski theory in weak field limits. To…
