点一下不认识的单词。
Scientists study active galactic nuclei, or AGNs. AGNs are very bright centers of some galaxies. They have big black holes that pull in gas and stars. A black hole is a space object with very strong gravity. It can pull everything close to it, even light.
Dr. Johannes Buchner talked about new results from the eROSITA telescope. This telescope found more than twenty thousand AGNs in just four days. Scientists use special methods to learn about the black holes in these AGNs. They found some black holes that are ten times bigger than usual in galaxies like our Milky Way.
Dr. Ryan Pfeifle spoke about dual AGNs. These happen when two galaxies come close and their black holes grow together. Scientists look for these dual AGNs in many ways, like using infrared light and radio images. They found many dual AGNs, some with three or more galaxies together. These discoveries help us understand how galaxies and black holes change over time.
In the future, new telescopes and surveys will help scientists study AGNs and galaxies more. They will learn more about how black holes and galaxies grow and change together. This research is very important for understanding our universe.

难句解析
- 1
They have big black holes that pull in gas and stars.
that 引导定语从句，修饰前面的 black holes，意思是“那些黑洞会吸入气体和恒星”。整句：这些星系中心有巨大的黑洞，会吞噬气体和恒星。
- 2
These happen when two galaxies come close and their black holes grow together.
when 引导时间状语从句，描述“当……时发生”。their black holes grow together 不是黑洞变大，而是指黑洞靠近并合并。整句：当两个星系靠近并且它们的黑洞合并时，就会出现双活动星系核。
- 3
They found many dual AGNs, some with three or more galaxies together.
some with three or more galaxies together 省略了主语和谓语，意思是“其中一些（双活动星系核）涉及三个或更多星系”。整句：他们发现了许多双活动星系核，其中有些甚至有三个或更多星系聚在一起。
