论文摘要
据报道，高能中微子事件ICECUBE-170922A与Blazar TXS 0506+056的关联闪闪发光，讨论了有关Blazars作为宇宙中微子的来源。在本文中，我们使用Roma-Bzcat的公开发布的ICECUBE数据和Blazar位置来测试中微子事件与Blazar位置之间的空间相关性。我们还根据FERMI监视的源列表将颞过滤器应用于数据，从而仔细检查了$γ$ ray通量和中微子通量之间的相关性。在检测到的ICECUBE-170922A / TXS 0506+056关联之前，我们没有发现令人信服的证据来证明Blazar是宇宙中微子的主要来源。虽然我们不排除IceCube-170922a和TXS 0506+056之间的关联，但我们获得的显着性水平不足以声称具有牢固的关联。如果这种关联是真实的，则需要一种特殊的物理状况，以使一小部分大麻成为明亮的中微子来源。
The reported association of high-energy neutrino event IceCube-170922A and blazar TXS 0506+056 has sparkled discussion about blazars as sources of cosmic neutrinos. In this paper, we use publicly released IceCube data and blazar locations from Roma-BzCat to test spacial correlation between neutrino events and blazar locations. We also scrutinize the correlation between $γ$-ray flux and neutrino flux of blazars by applying a temporal filter onto the data based on Fermi monitored source list. We find no compelling evidence to prove blazars as the main source of cosmic neutrinos, as known before the detected IceCube-170922A / TXS 0506+056 association. While we do not rule out the association between IceCube-170922A and TXS 0506+056, the significance level we obtained is not high enough to claim a strong association. If such an association is real, a special physical condition is desired to allow a small fraction of blazars to become bright neutrino sources.
