论文摘要
在本文中,我们在广义的爱因斯坦 - 卡丹 - 凯巴尔 - 塞亚玛(ECKS)重力理论中使用新的渐近平坦和球形对称解来研究弱重力透镜及其阴影铸造。为此,我们首先使用等离子体介质和真空中的高斯河网定理来计算广义ECKS黑洞的弱挠度角。接下来,通过使用纽曼 - 贾尼斯算法而无需复杂化的算法,我们得出了旋转的广义ecks黑洞,并在续集研究中得出了其阴影。然后,我们讨论ECKS参数对黑洞弱挠度角度和阴影的影响。简而言之,本文的目的是为ECKS理论做出贡献,并寻找证据以了解ECKS参数如何影响重力镜头。因此,我们表明,随着ECKS参数的增加,黑洞的弱挠度增加。
In this paper, we use a new asymptotically flat and spherically symmetric solution in the generalized Einstein-Cartan-Kibble-Sciama (ECKS) theory of gravity to study the weak gravitational lensing and its shadow cast. To this end, we first compute the weak deflection angle of generalized ECKS black hole using the Gauss-Bonnet theorem in plasma medium and in vacuum. Next by using the Newman-Janis algorithm without complexification, we derive the rotating generalized ECKS black hole and in the sequel study its shadow. Then, we discuss the effects of the ECKS parameter on the weak deflection angle and shadow of the black hole. In short, the goal of this paper is to give contribution to the ECKS theory and look for evidences to understand how the ECKS parameter effects the gravitational lensing. Hence, we show that the weak deflection of black hole is increased with the increase of the ECKS parameter.
