活动星系核的光谱监测:Ark 564和Arp 102 B的初步结果
Spectral monitoring of AGNs: Preliminary results for Ark 564 and Arp 102B
摘要:
本文介绍了对Ark 564和Arp 102 B两个宽线形状不同的活动星系核进行长期光谱监测的初步结果。方舟564是一个明亮的窄线Syfert 1(NLS 1)星系,具有相对窄的允许光发射线和高的Fe II/H $β$比,而Arp 102 B是一个宽线射电星系,具有宽的双峰巴耳末发射线。Ark 564的光谱在11年期间(1999-2009年)进行了观测,Arp 102 B的光谱在12年期间(1998-2009年)进行了观测,使用的是SAO 6米和1米望远镜(俄罗斯)和GHAO 2.1米望远镜(墨西哥卡纳内亚)。
英文摘要:
We present preliminary results of the long term spectral monitoring of two active galactic nuclei with different broad line shapes: Ark 564 and Arp 102B. Ark 564 is a bright nearby narrow line Syfert 1 (NLS1) galaxy with relatively narrow permitted optical emission lines and a high FeII/H$β$ ratio, while Arp 102B is a nearby broad-line radio galaxy with broad double-peaked Balmer emission lines. The spectra of Ark 564 were observed during 11-year period (1999-2009) and the spectra of Arp 102B in the 12-year period (1998-2009), with SAO 6-m and 1-m telescopes (Russia) and the GHAO 2.1-m telescope (Cananea, Mexico).
