摘要
最近，IceCube 报告了来自 Seyfert 星系 NGC 1068 的 neutrino 辐射。利用 13.1 年的 IceCube 数据，我们present 对北天区的 neutrino 源进行后续搜索。NGC 1068 仍为 110 个预选伽马射线源中最显著的 neutrino 源，同时也与北天区最显著位置一致。其能谱以无中断的幂律形式描述，谱指数为 。与前一结果一致，观测到的 neutrino 流量至少高出其伽马射线对应物两倍。此结果以及该源高 X 射线亮度的动因，促使我们从 Swift/BAT 光谱调查中挑选了 47 个 X 射线亮 Seyfert 星系（不在伽马射线源名单之列）。在对该集合进行 neutrino 辐射测试时，我们观察到来自 11 个源中的 3.3 超标，NGC 1068 不在样本中。我们的结果进一步加强了 X 射线亮活天体核是 neutrino 辐射源的证据。
