论文摘要
在天体物理学中，寻找最高能源宇宙射线的来源仍在继续。为了进一步的进步，不仅需要更好的观测值，而且还需要更现实的数值模拟。我们比较了IGMF中UHECR的数值测试模拟的不同方法，并表明所有方法都以粒子的扩散行为提供了正确的统计传播特性。通过收敛测试，我们表明该方法的必要要求有所不同，并最终揭示了所需的仿真时间的显着差异。
In astrophysics, the search for sources of the highest-energy cosmic rays continues. For further progress, not only ever better observatories but also ever more realistic numerical simulations are needed. We compare different approaches for numerical test simulations of UHECRs in the IGMF and show that all methods provide correct statistical propagation characteristics of the particles in means of their diffusive behaviour. Through convergence tests, we show that the necessary requirements for the methods differ and ultimately reveal significant differences in the required simulation time.
