Seyfert galaxy

Discovery of Six New X ray selected Quasars and a New Seyfert Galaxy from the ROSAT All Sky Survey

新发现的6个X选类星体和1个Seyfert星系

Then we found that the transformation from Quasar to Seyfert galaxy is so obvious that we could easily find the relation between them .

其中由类星体变化到Seyfert星系的过程非常明显，从它们的演化过程能够清晰看出二者之间演化过程的过渡。

According to the simplified unification model of active galactic nuclei ( AGN ), assuming that the gas in the NLR is spherically distributed , V-shape morphology ( ionization cone ) is expected to be observed in Seyfert 2 galaxy .

根据简化的活动星系核的统一模型，假设窄线区气体成球状分布，那么应观测到塞弗特2型星系的窄线区电离气体成V状（电离锥）。

The active galactic nucleus divides into QSO , Seyfert galaxies , radio galaxy , Blazar , Liner and so on .

活动星系核分为类星体，塞弗特星系，射电星系，Blazar，Liner等。

Seyfert galaxies divides into seyfert 1 and seyfert 2 galaxy , the two difference lies in the line width .

塞弗特星系又分为seyfert1和seyfert2星系，二者的差别在于线宽。
