Search for single sources of ultra high energy cosmic rays on the sky

In this paper we suggest a new way to identify single bright sources of UHECR on sky on top of background. We look for doublets of events at the highest energies, E > 6 × 10eV, and identify low energy tails, mainly deflected by the regular Galactic Magnetic Field (GMF). With the parameters adopted in this paper, for 68% of reconstructed sources, angular position is less than one degree from real one. Reconstruction of the deflection power of magnetic field is strongly affected by the turbulent component of the GMF and for typical values of 4μG near the Earth, one can reconstruct deflection power with 25% precision in 68% of cases.
