论文摘要

我们使用来自高海拔水分Cherenkov(HAWC)天文台的1523天数据提出了TEV伽马射线源的新目录。目录是对北部伽马射线天空的最敏感的调查,在几个TEV以上的能量上,与以前的HAWC目录相比,暴露的三倍。我们报告了65个以$ \ geq $ 5的sigma意义,以及每个来源的位置和频谱拟合。该目录包含八个在2HWC目录中没有对应物的资源,但在先前检测到的TEV发射器的$ 1^\ Circ $之内,而二十个来源则超过$ 1^\ Circ $远离任何先前检测到的TEV源。在这20个新来源中,有14个在第四\ textit {fermi}大面积望远镜目录中具有潜在的对应物。我们还探讨了3HWC源与ATNF Pulsar目录中的脉冲星和银河超新星残余目录中的脉冲星的潜在关联。

We present a new catalog of TeV gamma-ray sources using 1523 days of data from the High Altitude Water Cherenkov (HAWC) observatory. The catalog represents the most sensitive survey of the Northern gamma-ray sky at energies above several TeV, with three times the exposure compared to the previous HAWC catalog, 2HWC. We report 65 sources detected at $\geq$ 5 sigma significance, along with the positions and spectral fits for each source. The catalog contains eight sources that have no counterpart in the 2HWC catalog, but are within $1^\circ$ of previously detected TeV emitters, and twenty sources that are more than $1^\circ$ away from any previously detected TeV source. Of these twenty new sources, fourteen have a potential counterpart in the fourth \textit{Fermi} Large Area Telescope catalog of gamma-ray sources. We also explore potential associations of 3HWC sources with pulsars in the ATNF pulsar catalog and supernova remnants in the Galactic supernova remnant catalog.
