寻找超大质量黑洞的起源

Astronomers have identified a rapidly growing black hole in the early universe that is considered a crucial “missing link” between young star-forming galaxies and the first supermassive black holes, using data from the Hubble Space Telescope to make this discovery.

This artist’s impression is of a supermassive black hole that is inside the dust-shrouded core of a vigorously star-forming “starburst” galaxy. It will eventually become an extremely bright quasar once the dust is gone. Discovered in a Hubble deep-sky survey, the dusty black hole dates back to only 750 million years after the Big Bang.

天文学家利用哈勃太空望远镜的数据，在早期宇宙中发现了一个快速增长的黑洞，该黑洞被认为是年轻恒星形成的星系和第一个超大质量黑洞之间的一个关键的 “缺失环节”。

这幅艺术家的作品描绘的是一个超大质量黑洞，它位于一个活跃的恒星形成的“星爆”星系的尘埃覆盖的核心内部。一旦尘埃消失，它最终将成为一个极其明亮的类星体。哈勃望远镜在一次深空探测中发现了这一尘埃黑洞，它的历史可以追溯到宇宙大爆炸后7.5亿年。
