论文摘要
非线性电动力学被称为麦克斯韦电动力学在强场上的概括，并呈现出有趣的特征，例如治愈线性理论中存在的经典差异与一般相对论时。在本文中，我们考虑了Einstein-Nonlinelear-Maxwell领域中具有高阶磁性校正的渐近平坦Reissner-Nordström黑洞溶液。我们研究磁电荷参数对黑洞的影响，即。使用高斯河网定理的光子和巨大颗粒的弱挠度角。此外，我们应用Keeton-Petters形式主义来确认我们的弱挠度角度的结果。除了真空外，还探测了它们在不同介质（例如等离子体和暗物质）存在的影响。最后，我们使用Null-Geodesics方法检查了黑洞的阴影铸造，并研究了其面向内的薄积分磁盘。我们的推论表明了磁性电荷参数$ p $如何影响其他物理数量；因此，我们使用事件范围望远镜的观测值对此参数施加了一些约束。
Nonlinear electrodynamics is known as the generalizations of Maxwell electrodynamics at strong fields and presents interesting features such as curing the classical divergences present in the linear theory when coupled to general relativity. In this paper, we consider the asymptotically flat Reissner-Nordström black hole solution with higher-order magnetic correction in Einstein-nonlinear-Maxwell fields. We study the effect of the magnetic charge parameters on the black hole, viz. weak deflection angle of photons and massive particles using Gauss-bonnet theorem. Moreover, we apply the Keeton-Petters formalism to confirm our results of the weak deflection angle. Apart from vacuum, their influence in the presence of different media such as plasma and dark matter are probed as well. Finally, we examine the black hole shadow cast using the null-geodesics method and investigate its spherically in-falling thin accretion disk. Our inferences show how the magnetic charge parameter $p$ affects the other physical quantities; so, we impose some constraints on this parameter using the observations from the Event Horizon Telescope.
