论文摘要
在IceCube中测得的漫射性中微子通量与超能源宇宙射线（UHECR）通量相当，这导致了高能中微子和UHECR背景的统一起源的概念。我们构建了一个通用统一模型，以在$ \ gtrsim 10^{19} $ eV上解释UHECR数据，并在Photo-Meson生产过程的框架内具有超过$ \ sim100 $ tev的能量，并提供源属性的一般约束。必须实现具有$ \ gtrsim $ \ gtrsim的原位生产的源环境，其光学深度为$ 0.1 \ lyseSimτ_{pγ} \ Lessim 0.6 $，以将宇宙射线加速至Ultrahigh Energies。测得的宇宙射线和中微子的通量设置了源亮度及其速率密度的结合。尽管结果相当普遍，并且适用于未知的源人群，但是在提议的候选者中，如果血浆流出的Lorentz Bulk Bumk因子和宇宙Ray和磁场的均衡参数是合理选择的，那么低亮度伽马射线爆发（GRB）和潮汐破坏事件（TDES）可以满足要求。
The diffuse neutrino flux measured in IceCube is comparable with the ultrahigh-energy cosmic ray (UHECR) flux, which has led to the concept of a unified origin of high-energy neutrino and UHECR backgrounds. We construct a generic unification model of sources to explain UHECR data at $\gtrsim 10^{19}$ eV, and high-energy neutrinos with energies that exceed $\sim100$ TeV in the framework of photo-meson production processes, and provide general constraints on the source properties. A source environment with moderately efficient in-situ production of $\gtrsim 100$ TeV neutrinos with an optical depth of $0.1 \lesssim τ_{pγ}\lesssim 0.6$ must be realized to accelerate cosmic rays to ultrahigh energies. The measured fluxes of cosmic rays and neutrinos set a bound on the source luminosity and its rate density. Although the results are rather general and applicable to unknown source population, among the proposed source candidates, low-luminosity gamma-ray bursts (GRBs) and tidal disruption events (TDEs) could satisfy the requirements if the Lorentz bulk factor of plasma outflow and the equipartition parameters for cosmic rays and magnetic field are appropriately selected.
