摘要
HAWC 合作组发布了 TeV 源星表 2HWC，其中 19 个源未与任何已知高能（HE；E > 10 GeV）或甚高能（VHE；E > 300 GeV）源产生关联。该星表促使 MAGIC 与 Fermi-LAT 两台观测台站开展后续研究，旨在对宽能带伽马射线辐射进行探测。本文报道 HAWC、MAGIC 与 Fermi-LAT 针对三个未证认 HAWC 源——2HWC J2006+341、2HWC J1907+084* 与 2HWC J1852+013*——的首次联合工作结果。尽管在 HE 与 VHE 能段均未发现显著探测信号，本研究表明：对于 2HWC J1852+013*，需要至少 1 度延展（95% 置信水平）且 GeV 能段谱比由 HAWC 结果外推所得更硬；而对于其余源，仅最小 0.16 度延展（95% 置信水平）即可解释 HAWC 所提出的情形。此外，这些源为脉冲星风云的假设亦被详细探讨。
