论文摘要
在这项工作中，我们研究了具有典型的深色能量的Kerr-Newman Black Hole背景中的弱重力镜头。最初，我们通过使用高斯-BNNET定理来计算带有典型的深色能量的带电黑洞的偏转角。首先，我们假设赤道时空的赤道平面上的光线。在此过程中，我们首先找到相应的光学指标，然后计算高斯光学曲率以在高斯 - 骨网定理中使用。因此，我们计算出具有五次旋转带电的黑洞的光的挠度角。此外，我们还找到了具有典型的深色能量的Kerr-Newman黑洞的光挠度。为了验证我们的结果，我们通过使用零地测量方程来得出偏转角，该方程将降低到Kerr溶液的偏转角，并减少特定参数。此外，我们分析了偏转角$θ$ W.R.T的图形行为，以影响参数$ b $。我们的图形分析通过典型的深色能量的Kerr-Newman黑洞检索了有关偏转角度的各种结果。
In this work, we study the weak gravitational lensing in the background of Kerr-Newman black hole with quintessential dark energy. Initially, we compute the deflection angle of light by charged black hole with quintessential dark energy by utilizing the Gauss-Bnnet theorem. Firstly, we suppose the light rays on the equatorial plane in the axisymmetric spacetime. In doing so, we first find the corresponding optical metrics and then calculate the Gaussian optical curvature to utilize in Gauss-Bonnet theorem. Consequently, we calculate the deflection angle of light for rotating charged black hole with quintessence. Additionally, we also find the deflection angle of light for Kerr-Newman black hole with quintessential dark energy. In order to verify our results, we derive deflection angle by using null geodesic equations which reduces to the deflection angle of Kerr solution with the reduction of specific parameters. Furthermore, we analyze the graphical behavior of deflection angle $Θ$ w.r.t to impact parameter $b$. Our graphical analysis retrieves various results regarding to the deflection angle by the Kerr-Newman black hole with quintessential dark energy.
