Gravitational lensing in a space-time with cosmic string within the Eddington-inspired Born-Infeld gravity
arXiv:2306.12455 · doi:10.1142/S0219887824501871
Abstract
This study explores the deflection angle of photon rays or light-like geodesics within the framework of Eddington-inspired Born-Infeld (EiBI) gravity background space-time, taking into account the influence of cosmic strings. The primary focus lies in deriving the effective potential of the system applicable to both null and time-like geodesics, as well as determining the angle of deflection for light-like geodesics. Our analysis shows that the presence of cosmic strings induces modifications in these physical quantities, leading to shifts in their respective values.
