Search for patterns by combining cosmic-ray energy and arrival directions at the Pierre Auger Observatory

Mostrar todas las versiones(2)

Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with E ≥ 6×10<sup>19</sup> eV by analyzing cosmic rays with energies above E ≥ 5×10<sup>...

description Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with E ≥ 6×10<sup>19</sup> eV by analyzing cosmic rays with energies above E ≥ 5×10<sup>18</sup> eV arriving within an angular separation of approximately 15º. We characterize the energy distributions inside these regions by two independent methods, one searching for angular dependence of energy-energy correlations and one searching for collimation of energy along the local system of principal axes of the energy distribution. No significant patterns are found with this analysis. The comparison of these measurements with astrophysical scenarios can therefore be used to obtain constraints on related model parameters such as strength of cosmic-ray deflection and density of point sources.
