摘要
TeV 环形射线是围绕中年脉冲星的扩展性非常高能(0.1-100 TeV)伽马射线辐射。迄今仅在孤立脉冲星周围发现，但有论据表明也可能由毫秒脉冲星(MSP)产生。我们在 High Altitude Water Cherenkov(HAWC) 观测站 2565 天的数据中搜索来自射电和 GeV 伽马射线天文台的 MSP。我们没有从单个脉冲星发现显著辐射。通过组合所有 HAWC 可达的 MSP 的似然轮廓，我们的分析表明，MSP 群体周围的超标辐射与背景一致。我们的结果表明，MSP 在产生 TeV 环形射线方面不如孤立脉冲星高效。这一发现对解释银河中心 GeV 超身现象以及高纬度银河漫射辐射具有重要意义。
