论文摘要
最近的Icecube出版物声称，对宇宙中微子的观察至$ \ sim 10 $ tev，这加强了日益增长的证据，即10-100 TEV范围内的中微子通量意外大。这些中微子的任何可能来源还必须产生$γ$ ray的通量，该通量在通往地球的途中降低了能量，并有助于Fermi卫星测量的外层状$γ$ ray背景。在具有简约假设的定量多通用器分析中，我们在数据中找到了$ \ geq3σ$张力，到达$ \ sim5σ$，用于宇宙中微子的$ \ sim5σ$扩展到$ \ sim 1 $ tev，被解释为一组隐藏的宇宙射线加速器的证据。
The recent IceCube publication claims the observation of cosmic neutrinos with energies down to $\sim 10$ TeV, reinforcing the growing evidence that the neutrino flux in the 10-100 TeV range is unexpectedly large. Any conceivable source of these neutrinos must also produce a $γ$-ray flux which degrades in energy en route to the Earth and contributes to the extragalactic $γ$-ray background measured by the Fermi satellite. In a quantitative multimessenger analysis, featuring minimalistic assumptions, we find a $\geq 3σ$ tension in the data, reaching $\sim 5σ$ for cosmic neutrinos extended down to $\sim 1$ TeV, interpreted as evidence for a population of hidden cosmic-ray accelerators.
