摘要
我们报告了利用望远镜阵列实验的闪烁体表面探测器，在 2008 年 5 月至 2013 年 5 月期间，对北天区约 10 eV 中性粒子稳态点源进行搜索的结果。我们在北天区 0.5 EeV 以上未发现显著的点源超出。随后，我们还搜索了与 Fermi 明亮银河源的重合情况。在统计不确定性范围内未发现显著重合。因此，我们设定了中子通量的上限，对应于北天区 EeV 时 95% 置信水平下的平均通量 0.07 km yr。这是在假设点源情况下北天巡天中最严格的通量上限。天鹅座 X-3 (Cygnus X-3) 的中子通量在 95% 置信水平下的上限也被设定为 EeV 时 0.2 km yr。这一数值比之前的通量测量值低一个数量级。
