论文摘要
在这项工作中，我们旨在同时再现$ \ sim 10 \，\ Mathrm {tev} $在宇宙 - 射线质子光谱中，Dampe合作最近报道，光谱中断，以及$ \ sim 1 \，\ sim 1 \，\ Mathrm {tev} $ vibured sim {tev} $。在Lepton Spectrum中。这些功能被解释为附近隐藏宇宙射线加速器的一个特征。我们表明，只要扩散系数的刚度缩放具有$ \ sim 200 \，\ mathrm {gv} $，这种解释与偶极 - 肛门反应数据一致，这是由AMS-02 Collocation高准确度测量的。这种刚性依赖性扩散系数始终应用于大规模的扩散宇宙射线海，以及附近源注入的颗粒。
In this work we aim at reproducing, simultaneously, the spectral feature at $\sim 10 \, \mathrm{TeV}$ in the cosmic-ray proton spectrum, recently reported by the DAMPE Collaboration, together with the spectral break at $\sim 1 \, \mathrm{TeV}$ measured by H.E.S.S. in the lepton spectrum. Those features are interpreted as signatures of one nearby hidden cosmic-ray accelerator. We show that this interpretation is consistent with the dipole-anisotropy data as long as the rigidity scaling of the diffusion coefficient features a hardening at $\sim 200 \, \mathrm{GV}$, as suggested by the light-nuclei data measured with high accuracy by the AMS-02 Collaboration. Such rigidity-dependent diffusion coefficient is applied consistently to the large-scale diffuse cosmic-ray sea as well as to the particles injected by the nearby source.
