摘要
冰立方中微子天文台主要设计用于搜寻遥远天体物理源产生的高能（TeV--PeV）中微子。最近，一项对在仪器体积内相互作用的 ~TeV 中微子的搜寻提供了此类中微子各向同性通量的证据。在较低能量下，IceCube 收集了大量来自宇宙线空气簇射中介子弱衰变的中微子。我们在此展示了对 2010--2012 年期间 641 天数据中，在 IceCube 仪器体积内能量介于 1~TeV 和 1~PeV 之间的中微子相互作用的搜寻结果，首次将来自南方天空的中微子能量阈值降低到 10 TeV 以下，远低于先前高能分析的能量阈值。在南方天空，天体物理中微子在 10 TeV 以下仍占主导地位。从这些数据中，我们得出了对弥漫天体物理中微子能谱的新约束，，以及对大气中粲介子衰变产生的中微子通量的最强上限，在 90\% 置信度下为先前 IceCube 结果所用基准理论预测值的 1.52 倍。
