Galactic nucleus

Becauses of their intense physical process occurred mainly in their cores, or triggered by the cores,the study of the activities galaxy evolution focused on the evolution of active galactic nucleus(AGNs).

活动星系核(AGNs)是当代天体物理学研究的热门课题之一,活动星系作为星系的一个部分,由于其剧烈物理过程主要发生在其核心,或者是从核心引发出来,因此对活动星系的演化规律研究就集中在对活动星系核AGNs(ActiveGalactic Nucleus)的演化研究上。
