论文摘要
天文辐射（HADAR）实验的高海拔检测是基于大气Cherenkov成像技术的折射地面望远镜阵列。它通过大型孔径水镜系统发出的大量空气阵雨聚焦了Cherenkov的光，以观察到非常高的能量射线和宇宙射线。凭借大型视野（FOV）和低能阈值的优势，Hadar实验以大规模的天空扫描模式运行，以观察银河系来源。这项研究介绍了使用HADAR实验对Tevcat的TEVγ射线源的Sky调查的前景，并提供了一年的统计意义调查。模拟的结果表明，在Hadar FOV中检测到总共23个银河点源，包括5个超新星残留源和超级泡沫，四个脉冲星云源和14个不明的源，显着性大于5标准偏差（σ）。一年运行中蟹状星云的统计显着性达到346.0σ，而1TEV以上HADAR的一年积分敏感性约为1.3％-2.4％的通量，占螃蟹星云的通量。
The High Altitude Detection of Astronomical Radiation (HADAR) experiment is a refracting terrestrial telescope array based on the atmospheric Cherenkov imaging technique. It focuses the Cherenkov light emitted by extensive air showers through a large aperture water-lens system for observing very-high-energy-rays and cosmic rays. With the advantages of a large field-of-view (FOV) and low energy threshold, the HADAR experiment operates in a large-scale sky scanning mode to observe galactic sources. This study presents the prospects of using the HADAR experiment for the sky survey of TeV γ-ray sources from TeVCat and provids a one-year survey of statistical significance. Results from the simulation show that a total of 23 galactic point sources, including five supernova remnant sources and superbubbles, four pulsar wind nebula sources, and 14 unidentified sources, were detected in the HADAR FOV with a significance greater than 5 standard deviations (σ). The statistical significance for the Crab Nebula during one year of operation reached 346.0 σ and the one-year integral sensitivity of HADAR above 1TeV was ~1.3%-2.4% of the flux from the Crab Nebula.
