摘要
IceCube 中微子天文台已证实存在起源于天体物理的高能全天空中微子流。这一发现是利用在探测器 fiducial 区域内发生相互作用、且重建能量高于 60 TeV 的事件做出的，该样本通常被称为高能起点事件样本，或 HESE。我们借助额外 4.5 年数据、更新的冰川冰模型以及改进的系统误差处理，重新分析了 HESE 样本。本文详细描述了该样本，报告了最新的天体物理中微子流强测量，并给出了针对天体物理中微子的源搜寻。我们给出了这些观测与文献中提出的特定各向同性流强模型以及通用类幂律情景的相容性。假设 ，且中微子与反中微子流强相等，我们发现天体物理中微子能谱与未截断幂律相容，在 置信区间下优先谱指数为 。
