天文学家发现了质量相当于400亿个太阳的巨大黑洞

Astronomers believe they have discovered a supermassive black hole located 700 million light-years from Earth — and it has a mass 40 billion times that of the Sun.

天文学家称他们发现了一个超大质量黑洞，距离地球7亿光年，它的质量是太阳的400亿倍。

The black hole resides in Holmberg 15A, a so-called supergiant elliptical galaxy located within a group of over 500 galaxies called Abell 85, according to SciNews.

据Scinews称，黑洞位于霍姆伯格15a，一个所谓的超巨型椭圆星系，位于一个由500多个星系组成的群中，名为Abell85。

“This is the most massive black hole with a direct dynamical detection in the local Universe,” the researchers from the Max Planck Institute for Extraterrestrial Physics and University Observatory Munich told the publication.

来自马克斯·普朗克地外物理研究所和慕尼黑大学天文台的研究人员在该刊称：“这是本地宇宙中最巨大的黑洞，可以直接进行动态探测。”

“This black hole is not only one of the most massive known, it is also 4 to 9 times larger than expected given the galaxy’s bulge stellar mass,” they said.

“这个黑洞不仅是已知的最大的黑洞之一，考虑到这个星系膨胀的恒星质量，它比预期的还要大4到9倍。”

This supermassive black hole is twice as large as two other huge black holes, scientists noted.

科学家们指出，这个超大质量黑洞是其他两个大黑洞的两倍大。

“This is a remarkable observation of an extremely massive black hole at 40 billion solar masses. This makes it the most massive in our region of the universe, and one of the most massive ever found,” Andrew Coates, from University College London’s Department of Space and Climate Physics, told Newsweek.

“这是对一个具有400亿太阳质量的超大质量黑洞的惊人观测。”伦敦大学学院空间与气候物理系的安德鲁·考茨告诉《新闻周刊》说：“这使它成为我们宇宙中最庞大的区域，也是有史以来发现的最庞大的。”

The work was completed by astronomer Kianusch Mehrgan and her colleagues at the Max Planck Institute for Extraterrestrial Physics and University Observatory Munich.

这项工作是由天文学家凯纳什·梅尔根和她在慕尼黑马克斯普朗克地外物理研究所和大学天文台的同事完成的。

The findings will be published in the Astrophysical Journal.

研究结果将发表在《天体物理学杂志》上。
