论文摘要
我们使用10年的公开可用的ICECUBE数据来研究高能中微子与各种费米 - 拉特伽马射线样品之间的相关性。这项工作考虑了以下伽马射线样品：高能源（3FHL）的第三个费米 - 拉特目录，> 100GEV费米 - 拉特事件，LAT 12年源目录（4FGL），是活跃的银河系核（4LAC）（4LAC）和这些样品子集的第四个目录。对于每个样本，进行单源分析和堆叠分析。我们没有发现这些样品中的来源产生明显的高能中微子。从无效搜索结果中，我们推断出每个源总数的生产不超过2.5％-36％（对于置信度的95％，对于频谱指数为-2.5），ICECUBE的弥漫性中微子通量。由于我们使用的是Icecube中微子的较大（10年）数据集，因此与基于3年数据的数据相比，约束的提高了约2倍。
We use 10 years of publicly available IceCube data to investigate the correlations between high-energy neutrinos and various Fermi-LAT gamma-ray samples. This work considers the following gamma-ray samples: the third Fermi-LAT catalog of high-energy sources(3FHL), >100GeV Fermi-LAT events, LAT 12-year source catalog(4FGL), the fourth catalog of active galactic nuclei(4LAC) and subsets of these samples. For each sample, both a single-source analysis and a stacking analysis are performed. We find no indication that the sources in these samples produce significant high-energy neutrinos. From the null search results, we infer that each source population can produce no more than ~2.5%-36%(at the 95% confidence level, for a spectral index of -2.5) of the IceCube's diffuse neutrino flux. Since we are using a larger (10years) dataset of IceCube neutrinos the constraints are improved by a factor of ~2 compared to those based on 3 years of data.
