论文摘要
霍金，佩里和斯特罗辛格提出的超级翻译的黑洞可能会为信息悖论提供分辨率，该信息通常由复杂的时空度量标准定义，与Kerr Black Hole相比，时空对称性更低。在本文中，我们通过利用超级倾斜的4个速度和光线的轨迹来找出超级翻译的Schwarzschild黑洞的阴影。基于这种方法，我们发现光子球由于超倾斜的毛发而扭曲，阴影在投影平面上的位置被超级倾斜矢量移动，但是阴影的大小和形状与Schwarzshild黑洞的大小和形状保持不变。
The supertranslated black hole proposed by Hawking, Perry, and Strominger might provide a resolution to the information paradox, which is usually defined by a complicated space-time metric with even less space-time symmetries compared to Kerr black hole. In this paper, we figure out the shadow for the supertranslated Schwarzschild black hole by making use of supertranslated 4-velocities and the trajectories of the light rays. Based on this approach, we find that the photon sphere gets distorted due to the supertranslation hairs and the position of the shadow on the projection plane is shifted by the supertranslation vector, but the size and shape of the shadow remain the same as those of Schwarzschild black hole.
