VLA FIRST巡天的头尾射电源
Head Tail Radio Sources from VLA FIRST Survey
摘要：
头尾射电星系的研究是跟踪关联星系团的信息。利用1.4GHz的VLA FIRST巡天，我们探测到了607个新的HT射电源，其中398个是广角尾源（WAT），216个是窄角尾源（NAT）。NAT源通常具有开口角小于90度的“V”形结构，而对于WAT源，射流之间的开口角大于90度。我们发现，几乎80%的源与已知的星系团有关。我们提到了这些HT源的各种有用的物理性质。利用新发现的HT源的大样本，进行了各种统计研究。本文给出的光源的光度范围是$10^{39}$ $\leq$ $L_{1.4GHz}$ $\leq$ $10^{43}$ erg sec $^{-1}$。我们确定了193 WAT和104 NAT源的光学对应物。源的红移可达2.08。
英文摘要：
The study of Head Tail (HT) radio galaxies track the information of associated galaxy clusters. With the help of the VLA FIRST survey at 1.4 GHz, we detected 607 new HT radio sources, among them, 398 are Wide Angle Tail (WAT) and 216 are Narrow-Angle Tail (NAT) sources. NAT sources generally have `V' shaped structure with an opening angle less than ninety degrees and for WAT sources opening angle between the jets is more than ninety degrees. We found that almost 80 per cent of our sources are associated with a known galaxy cluster. We mentioned various useful physical properties of these HT sources. Taking advantage of a large sample of newly discovered HT sources, various statistical studies have been done. The luminosity range of sources presented in the current paper is $10^{39}$ $\leq$ $L_{1.4GHz}$ $\leq$ $10^{43}$ erg sec$^{-1}$. We identified optical counterparts for 193 WAT and 104 NAT sources. The sources are found up to redshift 2.08.
