扭曲的局部阴影

Distorted Local Shadows

Shohreh Abdolrahimi, Robert B. Mann, Christos Tzounis

摘要:

我们引入了局部阴影的概念,一个黑洞,并确定其形状的扭曲史瓦西黑洞的特定情况下。在考虑最低阶偶、奇多重矩的情况下,计算了Schwarzschild黑洞阴影的形变与畸变多重矩之间的关系。对于我们所考虑的多重矩的值的范围,视界的变形远小于其相应的阴影,这表明视界更“刚性”。我们非常意外地发现,视界的扁长变形引起阴影的扁扁变形,反之亦然。

英文摘要:

We introduce the notion of a local shadow for a black hole and determine its shape for the particular case of a distorted Schwarzschild black hole. Considering the lowest-order even and odd multiple moments, we compute the relation between the deformations of the shadow of a Schwarzschild black hole and the distortion multiple moments. For the range of values of multiple moments that we consider, the horizon is deformed much less than its corresponding shadow, suggesting the horizon is more `rigid'. Quite unexpectedly we find that a prolate distortion of the horizon gives rise to an oblate distortion of the shadow, and vice-versa.
