论文摘要
超高能宇宙射线在其加速器周围的相互作用自然可以解释观察到的UHECR的光谱和组成，包括脚踝下方的质子丰度。我们表明，UHECR源环境（例如温度，大小和磁场）的天体物理特性可以受到UHECR和中微子数据的约束。将其应用于具有简单结构的候选源，表明星爆星系与这些约束是一致的，但是星系簇可能与它们保持张力。对于诸如AGN和GRB之类的多组分系统，结果是指示性的，但是确定的结论需要定制分析。
Interactions of ultrahigh energy cosmic rays in the surroundings of their accelerators can naturally explain the observed spectrum and composition of UHECRs, including the abundance of protons below the ankle. We show that astrophysical properties of the UHECR source environment such as the temperature, size, and magnetic field can be constrained by UHECR and neutrino data. Applying this to candidate sources with a simple structure shows that starburst galaxies are consistent with these constraints, but galaxy clusters may be in tension with them. For multi-component systems like AGNs and GRBs the results are indicative but customized analysis is needed for definitive conclusions.
