论文摘要
在本文中，我们探讨了光子区域的光子区域和静态带电黑洞的旋转对应物的阴影，以前根据NULL和类似时间样的大地测量学对此进行了讨论。旋转的黑洞对电荷和自旋参数表现出强烈的敏感性，并且其阴影从植物的变化变为通过增加旋转参数来锐度。将阴影的垂直角直径与M87*的垂直角直径进行比较，我们发现，如果是旋转带电的Weyl Black Hole，则后者可能具有约$ 10^36 $的电荷来源。还提出了Ergosphere和静态极限的完全推导。
In this paper, we explore the photon region and the shadow of the rotating counterpart of a static charged Weyl black hole, which has been previously discussed according to null and time-like geodesics. The rotating black hole shows strong sensitivity to the electric charge and the spin parameter, and its shadow changes from being oblate to being sharp by increasing in the spin parameter. Comparing the calculated vertical angular diameter of the shadow with that of M87*, we found that the latter may possess about $10^36$ protons as its source of electric charge, if it is a rotating charged Weyl black hole. A complete derivation of the ergosphere and the static limit is also presented.
