标题： Search for spatial coincidence between IceCube neutrinos and radio pulsars

摘要： 我们使用公开可用的IceCube点源中微子事件目录，寻找射电脉冲星和超高能中微子之间的空间关联。 为此目的，我们使用无分箱最大似然方法，在ATNF目录中的每个脉冲星中搜索统计上显著的过量信号。 我们没有发现任何脉冲星的检测显著性远高于高斯分布所预期的，因此，我们得出结论，目前已知的任何脉冲星都不对IceCube探测到的弥散中微子通量做出贡献。 显示英文摘要

摘要： We search for a spatial association between radio pulsars and ultra-high energy neutrinos using the publicly available IceCube point source neutrino events catalog. For this purpose we use the unbinned maximum likelihood method to search for a statistically significant excess from each of the pulsars in the ATNF catalog. We do not find any pulsars with detection significance much higher than that expected from a Gaussian distribution, Therefore, we conclude that none of the currently known pulsars contribute to the diffuse neutrino flux detected by IceCube.
