摘要: We investigate the deflections of UHE protons by Galactic magnetic field (GMF) using four conventional GMF models in order to discuss positional correlation between arrival distribution UHECRs and their sources. coming from direction around center are highly deflected above 8° dipole during propagation space. However, bisymmetric spiral models, there directions which deflection angle is below 1°. One these toward Centaurus A, nearest radio-loud active galactic nucleus that a possible UHECR source candidate. On other hand, arriving anticenter generally less deflected, especially models. Thus, Northern Hemisphere, not including center, suitable for studies with The dependence on model parameters also investigated. angles dependent pitch field. distortion supergalactic plane GMF. Since strongly depends model, we can obtain information if Pierre Auger Observatory finds significant plane.
