摘要
脉冲星风云 (PWNe) 已被确立为数量最多的 TeV 伽马射线发射源类别。自发射以来，费米大视场望远镜 (LAT) 已确认五个高能 (100 MeV << 100 GeV) 伽马射线源为 PWNe，并探测到大量由年轻且高能脉冲星供能的 PWNe 候选体。丰富的多波段数据可用性以及费米 -LAT 提供的新结果，为我们寻找新的 PWNe 并探索已知 PWNe 中发生的辐射过程提供了机会。TeV 伽马射线未证认源 (UNIDs) 是寻找新 PWNe 的最佳候选体。利用 45 个月的费米 -LAT 高于 10 GeV 的能量数据，我们在银河平面 5 度范围内的 58 个 TeV PWNe 和 UNIDs 位置附近进行了分析，以建立对 PWNe 性质的新限制并寻找关于 UNIDs 本质的新线索。在 58 个源中，有 30 个被探测到，本文提供了它们高于 10 GeV 能量的伽马射线通量。在多波段背景下，谱能量分布 (SED) 和上限也提供了关于源性质的新信息，有助于区分发射情景，即区分是分类为脉冲星候选体还是 PWN 候选体。本文详细描述了六个新的 GeV PWN 候选体并与现有模型进行了比较，并展示了 GeV PWN 候选体作为脉冲星/PWN 系统特征函数的种群研究。
