论文摘要
最近，我们表明，由IceCube检测到的200 TEV高于200的高能中微子是在射线射线射击的中央区域的几个parsec中产生的，这是活跃的银河系核，喷气机指向我们。为了独立测试该结果并将分析扩展到更广泛的能量范围，我们将公共数据用于从七年的IceCube观察中进行所有中微子能量的公共数据。 IceCube点源的可能性图对通过其紧凑型无线电通量密度选择的统计完整样品的位置进行了分析。后一种分析具有3.0 Sigma的显着性，两项研究的综合审判意义为4.1 Sigma。相关性是由大量的大麻驱动的。与样本中未包含的较弱但在物理上不包含的物理上的来源一起，它们可以解释从MUON轨道分析中得出的整个Icecube天体中微子通量。中微子可以在相对论质子与Parsec-Scale尺寸Blazar喷气机中的X射线自动孔光子的相互作用中产生。
Recently we have shown that high-energy neutrinos above 200 TeV detected by IceCube are produced within several parsecs in the central regions of radio-bright blazars, that is active galactic nuclei with jets pointing towards us. To independently test this result and extend the analysis to a wider energy range, we use public data for all neutrino energies from seven years of IceCube observations. The IceCube point-source likelihood map is analyzed against the positions of blazars from a statistically complete sample selected by their compact radio flux density. The latter analysis delivers a 3.0 sigma significance with the combined post-trial significance of both studies being 4.1 sigma. The correlation is driven by a large number of blazars. Together with fainter but physically similar sources not included in the sample, they may explain the entire IceCube astrophysical neutrino flux as derived from muon-track analyses. The neutrinos can be produced in interactions of relativistic protons with X-ray self-Compton photons in parsec-scale blazar jets.
