论文摘要
我们测试了星爆星系的假设，作为超高能量宇宙射线和高能中微子的来源。使用Monte Carlo Code的修改版本{\ it Simprop}进行了超高的能量宇宙射线以及地球传播中的超高能量宇宙射线的相互作用，其中首次实施了来源环境中的HADRONIC过程。考虑到源源的恒星形成率分布，计算了超高的能量宇宙射线和高能量中微子的通量，并将其与观测值进行比较，并讨论了源特性的探索参数空间。我们发现，根据源环境中气体的密度，散布反应可能会超过中微子在源环境和半乳酸外空间中的光 - 光子相互作用中的中微子中的影响。
We test the hypothesis of starburst galaxies as sources of ultra-high energy cosmic rays and high-energy neutrinos. The computation of interactions of ultra-high energy cosmic rays in the starburst environment as well as in the propagation to the Earth is made using a modified version of the Monte Carlo code {\it SimProp}, where hadronic processes in the environment of sources are implemented for the first time. Taking into account a star-formation-rate distribution of sources, the fluxes of ultra-high energy cosmic rays and high-energy neutrinos are computed and compared with observations, and the explored parameter space for the source characteristics is discussed. We find that, depending on the density of the gas in the source environment, spallation reactions could exceed theoutcome in neutrinos from photo-hadronic interactions in the source environment and in the extra-galactic space.
