Search for ultra high energy cosmic ray sources

Earlier we suggested a new method to search for sources and anisotropy of the arrival directions of ultra high energy particles. Here using this method we analyzed the data of the Yakutsk EAS array and found that particle fluxes with energies E < 4.1019 eV come to the Earth from our Galaxy and the arrival directions of particles correlate with known pulsars. The chance probability of correlating particles with pulsars and the anisotropy of the distribution of particles is 10−4–10−5. We also analyzed the Telescope Array (TA) data with energies E < 4.1019 eV by our method and found that the maximum of the distribution of particles points to extragalactic sources but the direction of the maximum does not coincide with the maximum direction of the distribution of particles found by the authors of the Telescope Array data (the maximums of the arrival directions received by two different methods of analyses differ by about 10%).
