论文摘要
小角度散射状态中湍流间层状磁场中的UHECR传播对传播距离的距离远大于田间相干尺度的范围。扩散理论不起作用，在较小的距离（从几个和10-20个连贯尺度）上传播可能会出现意外影响。我们研究了该方案中UHECR的传播，这可能与中间的质量UHECR核和NG尺度尺度量表具有1 MPC相干性量表有关。我们发现，轨迹形成了一种非平凡的苛性腐蚀样模式，并且与各向同性偏差很强。因此，在给定距离下从源的通量测量将取决于观察者的位置。
UHECR propagation in a turbulent intergalactic magnetic field in the small-angle scattering regime is well understood for propagation distances much larger than the field coherence scale. The diffusion theory doesn't work and unexpected effects may appear for propagation over smaller distances, from a few and up to 10-20 coherence scales. We study the propagation of UHECRs in this regime, which may be relevant for intermediate mass UHECR nuclei and nG scale intergalactic magnetic fields with 1 Mpc coherence scale. We found that the trajectories form a non-trivial caustic-like pattern with strong deviation from isotropy. Thus, measurements of the flux from a source at a given distance will depend on the position of the observer.
