Cross correlation of UHECRs and local matter distribution taking into account the energy attenuation due to interaction with the cosmic background radiation
Popis výsledku v původním jazyce
The arrival direction distribution of ultra-high energy cosmic rays (UHECRs) is a key element to understand their sources and composition as well the galactic and extragalactic magnetic fields. The particles that arrive on Earth with energies above ∼50 EeV must be originated in sources nearby us as a result of the GZK effect. Furthermore, if these particle are protons and the magnetic fields along their propagations until Earth are not too large, we expect that their arrival directions are correlated with their sources. The cross-correlation used in cosmology is a good tool for studying such anisotropies in the cosmic ray data. In this work, assuming a proton composition, we modify the Landy-Szalay cross-correlation estimator in order to take into account the energy losses in the cosmic ray propagation due to its interaction with the background radiation.n
