Gravitational lensing by Morris-Thorne–type wormhole space-time with cosmic strings

Abstract

Abstract In this paper, we study the deflection angle of photon light in Morris-Thorne–type wormhole space-time with a cosmic string. It is shown that the angle of deflection of photon light as well as the effective potential (time-like or light-like geodesics) of the system is influenced by the cosmic string and is higher compared to the known result.
