旋转黑洞在标准背景屏幕上的阴影

Shadow of rotating black holes on a standard background screen

Serge V. Repin, Dmitry A. Kompaneets, Igor D. Novikov, Valeriya A. Mityagina

摘要:

我们在标准背景屏幕上呈现出黑洞阴影的形状,因为它是由遥远的观察者记录的。屏幕是一个无限的平面,发射的量子均匀分布到一个半球。发射源被认为是光学薄的和光学厚的。结果表明,黑洞阴影的形状主要取决于该平面与远距离观察者视线之间的夹角。还提供了该角度的不同值的阴影形状。Schwarzschild和Kerr度量都被考虑。

英文摘要:

We present the shape of the black hole shadow on the standard background screen as it is registered by the distant observer. The screen is an infinite plane, emitting the quanta uniformly distributed to a hemisphere. The source of emission is considered to be optically thin and optically thick. It is shown that the shape of a black hole shadow depends crucially on the angle between the plane and the view line to the distant observer. The shadow shapes for the different values of this angle are also presented. Both Schwarzschild and Kerr metrics are considered.
