Observation of a large-scale anisotropy in the arrival directions of cosmic rays above 8 x 1018 eV
Original language description
Cosmic rays are atomic nuclei arriving from outer space that reach the highest energies observed in nature. Clues to their origin come from studying the distribution of their arrival directions. Using 3 x 10(4) cosmic rays with energies above 8 x 10(18) electron volts, recorded with the Pierre Auger Observatory from a total exposure of 76,800 km(2) sr year, we determined the existence of anisotropy in arrival directions. The anisotropy, detected at more than a 5.2s level of significance, can be described by a dipole with an amplitude of 6:5(-0.9)(+1.3) percent toward right ascension alpha(d) = 100 +/- 10 degrees and declination delta(d) = -24(-13)(+12) degrees. That direction indicates an extragalactic origin for these ultrahighenergy particles.n
