Deflections of cosmic rays in a random component of the Galactic magnetic field

We express the mean square deflections of the ultra-high energy cosmic rays (UHECR) caused by the random component of the Galactic magnetic field (GMF) in terms of the GMF power spectrum and use recent measurements of the GMF spectrum to estimate them quantitatively. We find that deflections due to...

description We express the mean square deflections of the ultra-high energy cosmic rays (UHECR) caused by the random component of the Galactic magnetic field (GMF) in terms of the GMF power spectrum and use recent measurements of the GMF spectrum to estimate them quantitatively. We find that deflections due to the random field typically constitute 0.03-0.3 of the deflections which are due to the regular component and depend on the direction on the sky. They are small enough not to preclude the identification of UHECR sources, but large enough to be detected in the new generation of UHECR experiments.

We use recent measurements of the GMF spectra in several sky patches to estimate the deflections quantitatively. We find that deflections due to the random field constitute $0.03-0.3$ of the deflections which are due to the regular component and depend on the direction on the sky. They are small enough not to preclude the identification of UHECR sources, but large enough to be detected in the new generation of UHECR experiments.astro-ph/0411669oai:cds.cern.ch:8071932004-11-24
