论文摘要
最近，事件地平线望远镜合作报道了银河中心超级质量黑洞射手座的第一张图像。我们尝试使用这种新的阴影观察来测试黑洞无头发定理的有效性。考虑到具有最小耦合标量字段的爱因斯坦 - 马克斯韦 - 克莱因 - 凯琳 - 基因理论，我们发现我们的数值结果与无发性定理的预测一致。但是，我们不能排除在某些特殊情况下可能存在带标量头发的黑洞的可能性。
Recently, the Event Horizon Telescope collaboration has reported the first image of the supermassive black hole Sagittarius in the Galactic Center. We attempt to test the validity of the no-hair theorem of black holes using this new shadow observation. Considering the Einstein-Maxwell-klein-Gordon theory with a minimally-coupled scalar field, we find that our numerical result is consistent with the prediction of the no-hair theorem. However, we can not rule out the possibility that black holes with scalar hair may exist in some special cases.
