Propagation of Ultra-High Energy Cosmic Rays from Sources in the Super-Galactic Plane

摘要: We have performed detailed numerical simulations on the propagation of UHE protons in energy range E = (1019.5–1022.0) eV a relatively strong extragalactic magnetic field with strength B (10–100)nG within about 40Mpc. In this case, deflection angles UHECRs become so large that no counterparts problem can be simply solved. As for source distribution, we assumed it is proportional to number distribution galaxies Greisen–Zatsepin–Kuzmin sphere. found many clusters, meaning small-scale anisotropy, our simulations. It has also been shown observed spectrum well reproduced models without any fine-tuned parameter. used correlation value order investigate statistically similarity between arrival directions and galaxies. each parameter set begins converge when detected events becomes O(103). Since expected counts by experiment next generation, such as TA, HiRes, Auger, EUSO, are thought 103, will able check very near future whether correlated Super-Galactic Plane or not. Compared AGASA data, significant anisotropy analyses first second harmonics. This may originate from an incompleteness ORS database. solved if slightly changed. For example, assume come some galaxies, AGNs radio
