Abstract

In this work we calculate the angular deflection of light in the strong field limit in two spacetimes which were previously studied within the Eddington-inspired Born-Infeld gravity, namely, a black hole and a wormhole, both with topological charge. We show that the presence of the parameters characterizing Eddington-inspired Born-Infeld gravity and the topological charge promote significant changes in the angular deflection of light with respect to that one obtained in Schwarzschild spacetime. Using the expression for angular deflection in the strong field limit, we calculate the position and magnification of the respective relativistic images.
