摘要:

本文介绍了利用RTT 150望远镜对硬X射线源IGRJ 18257 -0707的光谱观测,对硬X射线源IGRJ 18257 -0707进行光学鉴别的结果。利用钱德拉观测确定的X射线源的精确位置,使我们能够把这个源与在其光谱中显示宽H_α发射线的微弱光学天体(m_R=~20.4)联系起来。因此,我们得出结论,源IGRJ 18257 -0707是一个1型塞弗特星系在红移z=0.037。

英文摘要:

We present the results of the optical identification of hard X-ray source IGRJ18257-0707 trough the spectroscopic observations of its optical counterpart with RTT150 telescope. Accurate position of the X-ray source, determined using Chandra observations, allowed us to associate this source with the faint optical object (m_R=~20.4), which shows broad H_αemission line in its optical spectrum. Therefore we conclude that the source IGRJ18257-0707 is a type 1 Seyfert galaxy at redshift z=0.037.
