论文摘要
我们在EHT协作最近提出的超级质量黑洞Sgra*图像中阐明了黑点的物理起源。有人认为，这个黑点显着比经典的黑洞阴影小，是事件地平线的北半球。经典的黑洞阴影在Sgra*的图像中看不见。 Sgra*图像中的黑点投影在天体球体上经典的黑洞阴影的位置。这个黑点的外边界是事件范围地球仪上的赤道。
We elucidate the physical origin of the dark spot in the image of supermassive black hole SgrA* presented very recently by the EHT collaboration. It is argued that this dark spot, which is noticeably smaller than the classical black hole shadow, is the northern hemisphere of the event horizon globe. The classical black hole shadow is unseen in the image of SgrA*. The dark spot in the image of SgrA* is projected within the position of the classical black hole shadow on the celestial sphere. The outer boundary of this dark spot is an equator on the event horizon globe.
