论文摘要
近年来发现了明亮的无线电广播电台是高能中微子来源的证据。但是，仍需要确定这些颗粒如何以及在何处产生这些颗粒的细节。在本文中，我们添加了从2020-2022的14个新的Icecube事件，以更新我们对中微子 - 尼斯中音连接的分析。我们通过利用2009 - 2022年的71个类似轨道的高能ICECUBE事件来测试和完善早期发现。我们将它们与由3412个通过紧凑的无线电发射选择的3412个播出外无线电源的完整样本相关联。我们证明了中微子在统计上与射线射击，其后p值为3*10^-4。除了这项统计研究之外，我们还确认了以前的个体中微子 - 尼斯 - 基础关联，查找并讨论了几个新的中微子。值得注意的是，PKS 1741-038较早选择，并于2022年从其方向检测到第二个中微子。 PKS 0735+168在整个电磁光谱中经历了一个重大的耀斑，与2021年的中微子到达。
Evidence for bright radio blazars being high-energy neutrino sources was found in recent years. However, specifics of how and where these particles get produced still need to be determined. In this paper, we add 14 new IceCube events from 2020-2022 to update our analysis of the neutrino-blazars connection. We test and refine earlier findings by utilising the total of 71 track-like high-energy IceCube events from 2009-2022. We correlate them with the complete sample of 3412 extragalactic radio sources selected by their compact radio emission. We demonstrate that neutrinos are statistically associated with radio-bright blazars with a post-trial p-value of 3*10^-4. In addition to this statistical study, we confirm previous individual neutrino-blazar associations, find and discuss several new ones. Notably, PKS 1741-038 was selected earlier and had a second neutrino detected from its direction in 2022; PKS 0735+168 has experienced a major flare across the whole electromagnetic spectrum coincidently with a neutrino arrival from that direction in 2021.
