We don’t observe more mergers in the AGN host galaxies,” Cisternas said.───我们没有观测更多AGN母星系的吞并。
AGN changes in the optical spectra and light changes between standard Is there some relationship?───星系核的光学谱变化与光变时标之间是否存在某种关系？
The result of this paper may be applied to the accretion discs in quasars and AGN.───本文结果可用于类星体和星系核吸积盘。
The survey is sensitive to AGN up to 650 million light-years away and has uncovered dozens of previously unrecognized systems.───这项调查是敏感的活动星系核高达650亿光年远，并发现了先前未知的系统几十人。
Astronomers call the most energetic of these objects active galactic nuclei, or AGNs, after the powerful jets of radiation they spew.───天文学家们将这些观测物中最活跃的那些，依据它们喷吐出的强力迸发的辐射称作活动星系核，英文缩写为AGN。
LK can be considered as a direct evidence for AGN feedback in galaxy groups and clusters.───LK相关性可作为星系群和星系团中AGN反馈加热的直接证据。
She argues that once a hole is in place, gas naturally flows into the galaxy core, fueling an AGN.───她认为只要黑洞处在适当的位置，气体自然而然会流往星系核心，而为AGN加添燃料；
Structure function and auto-correlation function are major tools for studying the variability properties of AGN samples.───结构函数和自相关函数等是研究活动星系核样本光变性质的主要方法。
But for decades only about 1 percent of AGN seemed to be associated with galaxy mergers.───但数十年观测发现仅约百分之一的活动星系核与星系合并有关联。
Hasinger and his colleagues have combined XMM and Infrared Space Observatory measurements of the Lockman Hole, putting a lower limit— 15percent—on the AGN contribution to the infrared background.
