Gravitational lensing by deformed Horava-Lifshitz black hole in rainbow gravity

Physics Letters B
In this study, we investigate the gravitational lensing effects of deformed Horava-Lifshitz black holes, considering both strong and weak-field limit approximations and incorporating the impact of rainbow functions.

Deflection angle of regular black holes in nonlinear electrodynamics: Gauss-Bonnet theorem, time delay, shadow, and greybody bound

Physics Letters B
In this article, we study the weak gravitational lensing in the background of regular, static, spherically symmetric black hole solutions of Einstein’s standard general relativity coupled with nonlinear electrodynamics.
