The possible sources of ultra-high energy cosmic rays

A possible correlation between the arrival directions of ultrahigh energy cosmic rays by using EAS array data and point galactic sources of radio and gamma radiations, pulsars, has been considered. At mean cosmic rays energy of ~ 10 19 eV, a correlation between their arrival directions and pulsars located in the direction of the Local Arm of the Galaxy is found. According to our estimations, the chance probability is 2 × 10 −4 . The obtained results are discussed.
