Deflections of UHECRs in the Galactic magnetic field
Original language description
We report results of the first comprehensive, high resolution study of the deflections of UHECRs using a realistic model of the Galactic magnetic field and extending to sufficiently low rigidities, R (math)E/Z >= 10(18) V, to describe Fe in the UHE energy range above similar to 55 EeV, or the mixed composition reported by the Pierre Auger Collaboration at the energy of the observed dipole anisotropy. We use the Jansson-Farrar (JF12) model, which has both a large scale coherent and a structured random component, and determine deflections for fifteen rigidities from 10(18.0) to 10(20.0) V, for two different coherence length choices for the random component, L-coh = 30 pc and 100 pc. We also check the sensitivity of UHECR deflections to the particular realization of the random field, for 3 rigidity values. For each rigidity and field model studied, the UHECR arrival direction distribution is determined for an arbitrary source direction, by inverting the trajectories of > 5 x 10(7) isotropically-distributed anti-CRs of the given rigidity, which we backtrack using the code CRT. We present skyplots and tables characterizing the arrival directions, for representative 1 degrees sources.
