用TACTIC望远镜在2004- 2007年期间搜寻TeV $γ$ -来自H1426 +428的射线
Search for TeV $γ$ -rays from H1426+428 during 2004-07 with the TACTIC telescope
摘要：
BL Lac天体H1426+428（$z\equiv 0.129$）是TeV $γ$射线的一个已确定的来源，从该天体探测到这些光子对于估计河外背景光（EBL）以及了解活动星系核喷流中的粒子加速和$γ$射线产生机制也具有重要意义。我们在2004年、2006年和2007年用$γ$ Mt.阿布，印度。对这些数据的详细分析并没有表明从源方向存在任何统计上显著的TeV $γ$射线信号。因此，我们在3 $σ$显著性水平下对积分$γ$射线通量设置了$\leq1.18\times10^{-12}$ $photons$ $cm^{-2}$ $s^{-1}$的上限。
英文摘要：
The BL Lac object H1426+428 ($z\equiv 0.129$) is an established source of TeV $γ$-rays and detections of these photons from this object also have important implications for estimating the Extragalactic Background Light (EBL) in addition to the understanding of the particle acceleration and $γ$-ray production mechanisms in the AGN jets. We have observed this source for about 244h in 2004, 2006 and 2007 with the TACTIC $γ$-ray telescope located at Mt. Abu, India. Detailed analysis of these data do not indicate the presence of any statistically significant TeV $γ$-ray signal from the source direction. Accordingly, we have placed an upper limit of $\leq1.18\times10^{-12}$ $photons$ $cm^{-2}$ $s^{-1}$ on the integrated $γ$-ray flux at 3$σ$ significance level.
