论文摘要
在第二个HAWC Gamma-ray目录中报告了TEV点源2HWC J2006+341的发现。我们在此处介绍了该来源的后续研究。 TEV发射最好由具有软光谱的扩展源描述。在GEV能量,在费米 - 拉特数据中显着检测到扩展源。匹配位置,尺寸和光谱表明两个伽马射线检测对应于同一源。考虑到发射的起源的不同方案,我们排除了与PULSAR PSR J2004+3429的关联,如果所需的极端能量,则位于10.8 kpc的距离。
The discovery of the TeV point source 2HWC J2006+341 was reported in the second HAWC gamma-ray catalog. We present a follow-up study of this source here. The TeV emission is best described by an extended source with a soft spectrum. At GeV energies, an extended source is significantly detected in Fermi-LAT data. The matching locations, sizes and spectra suggest that both gamma-ray detections correspond to the same source. Different scenarios for the origin of the emission are considered and we rule out an association to the pulsar PSR J2004+3429 due to extreme energetics required, if located at a distance of 10.8 kpc.
