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。
Advanced civilizations may live safely inside the super-massive black holes in the galactic nuclei without being visible from the outside.
先进的外星文明可能安全生活在星系核中的特大质量黑洞里，而不被外界发现。
Richard Larson, a Yale astronomer who studies star formation in galactic nuclei, says galaxies can go through several quasar phases during their lives.
理查德·拉尔森，一个耶鲁的天文学家，他研究星系核中的恒星结构，他说，星系在整个生命史中，可能会经历好几个类星体的阶段。
The high energy radiation mechanism research of active galactic nuclei is a key to understanding their structure, evolution features and origin of central drive.
活动星系核的高能辐射机制研究对于揭示其结构和演化特征以及中央驱动之谜具有极其重要的意义。
We discuss in detail on the focus between the arguments of the above two basic views which are very closely related to the X-ray radiation of active galactic nuclei.
并对两派观点争论的焦点问题进行了详细的阐述。这个焦点问题与活动星系核的X射线辐射紧密相关。
Most galaxies are like that, as it happens, but there are a few rougher neighborhoods where the black holes cause their share of mayhem in the form of active galactic nuclei (AGNs).
大部分星系都是如此，但有一些粗暴的邻居的黑洞让它们以活动星系核(agn)的形式对外散布伤害。
The existence of black holes in the universe is well supported by astronomical observation, particularly from studying supernovae and X-ray emissions from active galactic nuclei.
天文学观察很好地支持了宇宙中黑洞存在，特别从研究来自活跃的银河核心超新星和X光辐射。
The team chose 140 active galactic nuclei, or AGNs, by selecting galaxies that emit a lot of X-rays, which can Pierce the galactic gas and dust that might otherwise block the nuclei from view.
课题小组选择了140个活动星系核，或简称agns，这些星系都放射出大量的X射线，X射线能穿透阻挡观测的气体和尘埃。
Simulations have found that black holes and galaxies grow together. Some observations even suggested that galaxies with active galactic nuclei were slightly distorted, a sign of a recent collision.
仿真的结果表明，黑洞是和星系一同成长的，一些观测结果甚至显示一些含有活动星系核的星系有轻微的扭曲，这是近期发生碰撞的标志。
Astronomers studied NGC6240 because it produced unexplained bursts of X-rays that appeared to come from one of two nuclei at the galactic center.
天文学家之所以研究NGC6240，是因为发现该星系中心有两个核，此中一个不竭爆发出难以解释的X线。
Astronomers studied NGC6240 because it produced unexplained bursts of X-rays that appeared to come from one of two nuclei at the galactic center.
天文学家之所以研究NGC6240，是因为发现该星系中心有两个核，此中一个不竭爆发出难以解释的X线。
