论文摘要
在这项工作中，我们计算了两个空间中强场限制中光的角度偏转，这些距离先前在爱丁顿风格的出生式重力（EIBI）中进行了研究，即黑洞和一个虫洞，都带有拓扑电荷。我们表明，相对于在Schwarzschild时空中获得的参数，表征EIBI和拓扑电荷的参数的存在促进了光的角度偏转的显着变化。使用该表达式在强场极限中进行角挠度，我们计算相对论图像的位置和放大倍率。
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 (EiBI), namely, a black hole and a wormhole, both with topological charge. We show that the presence of the parameters characterizing EiBI 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.
