论文摘要
最近，成功捕获了Galaxy M87中心的超大质量黑洞的第一个真实图像。为了解释观察到的强大喷气机和电磁积累磁盘的行为，已经考虑了事件范围的望远镜协作。为了证明这些现象是合理的，我们正在寻求一个精确的解决方案，用于扰动的rissner-nordstrom黑洞，该黑洞被无力的场电动力学盘包围。尽管带电的黑洞是一个玩具模型，但通过将电荷趋于零，可以立即获得扰动，旋转，Schwarzschild的结果。关于无力场电动力学作为在不同类别的黑洞中扰动的来源的确切解决方案可能是开放问题之一。为了找到该解决方案，计算了在切线和弯曲背景中的能量弹药张量之外的不同麦克斯韦的标量。这样，考虑了众所周知的纽曼 - 芬罗形式主义。
Recently the first real image of the supermassive black hole at the heart of the galaxy M87 successfully has been captured. To explain the behavior of both the observed powerful jets and the electromagnetic accretion disk the Blandford Znajek mechanism, by the Event Horizon Telescope collaboration, has been considered. To justify these phenomena we are seeking an exact solution for a perturbed Rissner-Nordstrom black hole surrounded by a force-free field electrodynamics accretion disk. Although a charged black hole is a toy model, by tending the charge to zero one can obtain the results for a perturbed, rotating, Schwarzschild one immediately. Finding an exact solution in regards to the force-free field electrodynamics as a source for perturbations in different classes of the black holes is may one of the open problems yet. Here to find the solution, different Maxwell's scalars besides the energy-momentum tensor in both tangent and bend backgrounds are calculated. In doing so, the well known Newman-Penrose formalism is considered.
