摘要
我们呈现了利用最近建成的高海拔水切伦科夫天文台（HAWC）实现的首个TeV伽马射线源目录。它是目前运行中灵敏度最高的宽视场TeV望远镜，其一年巡天灵敏度约为蟹状星云通量的5-10%。凭借大于1.5 sr的瞬时视场和大于90%的占空比，它持续巡天并监测能量在数百GeV至数十TeV间的伽马射线天空。HAWC位于墨西哥北纬19度，于2015年3月建成。在此，我们呈现2HWC目录，这是利用完整HAWC探测器实现首次源搜索的结果。该目录基于507天数据，代表了迄今针对如此大天区比例最灵敏的TeV巡天。共探测到39个源，预期由于背景涨落导致的污染为0.5。这些源中有16个距离任何先前报道的TeV源超过1度。报告了源列表，包括位置测量、能谱测量及不确定性。探测到的源中，7个可能与脉冲星风云相关，2个与超新星遗迹相关，2个与耀变体相关，其余23个尚无确切证认。
