摘要
最近的 IceCube 检测到来自邻近活跃星系 NGC 1068 的 TeV 级中子暴露，表明活跃星系 (AGN) 可能对astrophysical 中子暴露的扩散flux做出重要贡献。NGC 1068 的缺乏 TeV 级射线表明中子产生发生在超大质量黑洞附近，此处辐射密度很高，导致射线被消耗。因此，类似来源的潜在中子暴露预计不会与高能射线相关。盘-冠模型预计，圣太极星系的中子暴露应与 keV X 射线相关，因为后者是冠活动的探针。利用2011至2021年间 IceCube 记录的北天通过性轨迹事件，我们报告了从27个包含在BAT活跃星系光谱调查(BASS)中的额外圣太极星系进行的单个和聚合中子信号搜索的结果。除了通用的单一幂律外，我们评估了盘-冠模型预测的光谱。假设所有来源都与 NGC 1068 本身在本质上相似，我们的发现约束了北半球 X 射线亮型圣太极星系的集体中子暴露，但同时也显示出可能与对象 NGC 4151 和 CGCG 420-015 相关的异常中子暴露。这些异常相对于背景预期具有 2.7显著性。
