Optical variability is a common property of AGNs, Which provides a potentially powerful tool to probe the physics of AGNs.
光变是活动星系核（AGN） 的共同特征， 光变规律的研究已成为人类探索活动星系核物理的有力手段。
My research interests mainly include quasars and active galactic nuclei (AGNs), supermassive black holes and their accretion physics.
我的研究兴趣主要包括类星体与活动星系核、超大质量黑洞以及它们的吸积物理。
Now they just needed to figure out whether a galaxy was distorted or not, in order to determine whether misshapen galaxies were more likely to have AGNs.
现在他们只需要搞清楚星系是否被扭曲了，就能确认畸形星系是否更容易产生agn。
