论文摘要
我们使用公开可用的IceCube点源中微子事件目录来搜索无线电脉冲星和超高能量中微子之间的空间关联。为此，我们使用未链接的最大似然方法来搜索ATNF目录中每个脉冲星的统计学意义过剩。我们没有发现任何具有检测显着性的脉冲星要比高斯分布所预期的要高得多，因此，我们得出的结论是，当前已知的脉冲星均未促进由IceCube检测到的弥漫性中微子通量。
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.
