So for years no one could be certain if supermassive black holes really did exist at the heart of these strange active galaxies.
因此这么多年仍无人能确定这些异常活跃的星系中心是否有超级黑洞.
The satisfactory performance for classification and knowledge discovery has been obtained by the proposed novel classifier over active galactic nucleus（AGNs） and active galaxies（AGs） data.
通过对活动星系与活动星系核实验表明，该方法无论对分类还是对知识发现都是非常有效的。
Galaxies can be divided into two classes: normal galaxy (NG) and active galaxy (AG).
星系通常分为正常星系(NG)与活动星系(AG)两类。
As a result, while the small, bright nucleus is typical of the Seyfert class of active galaxies, M94 is also known as a starburst galaxy.
在中心的小亮核心是典型的西佛星系(Seyfert)，而M94亦称为星暴增星系。
