Supernova remnants (SNRs) are the primary candidates for the explanation of the cosmic ray flux up to 1015 eV. In this project, cosmic ray transport will be simulated, including discrete SNRs with individually modeled spectra. The simulated leptonic and hadronic cosmic ray spectra after propagation will be compared with the observed spectra. In particular, the inclusion of discrete sources and convection in the transport simulation is expected to contribute further to the explanation of some of the observed anomalies, like the hadronic cosmic ray anisotropy at 10 TeV, high-energy electron and positron spectra, and the haze photon structure from towards the Galactic center

超新星遗迹（SNRs）是解释高达1015 eV的宇宙线通量的主要候选者。在这个项目中，将模拟宇宙射线传输，包括离散信噪比与单独建模的光谱。模拟的轻子和强子宇宙线传播后的光谱将与观测到的光谱进行比较。特别是，在输运模拟中包括离散源和对流，预计将有助于进一步解释一些观察到的异常，如10 TeV的强子宇宙线各向异性，高能电子和正电子光谱，以及朝向银河系中心的雾光子结构
