چکیده
|
A model of turbulent galactic magnetic elds was developed in which, the type of turbulence were considered to be Kolmogorov. We tested the e ect of this model on an isotropically distributed ux of ultra high energy cosmic ray in the extragalactic space. To do this, a giant Galactic halo (radius of 100Mpc) was considered. Regular and random components of the Galactic Magnetic Fields were considered to have the mean observed relevant values and also satisfy a Kolmogorov eld type. The deviation from isotropy then were calculated considering the propagation of ultra high energy protons in such a magnetic eld and results were discussed to show how isotropic is the ux of ultra high energy cosmic rays in the extragalactic space. It is seen that considering an isotropic ux of ultra high energy cosmic rays in the intergalactic space for di erent choices of galactic magnetic eld is not consistence with the distribution of observed ultra high energy events.
