Medium-scale anisotropies in the arrival directions of UHECRs observed by the Pierre Auger Observatory
Original language description
The most prominent obstacle to identifying the sources of UltraHigh-Energy Cosmic Rays (UHECRs) is their incredibly low flux. For this reason, the Pierre Auger Observatory covers an area of ∼3000 km2 and, in its 17 years of operation, has collected over 2600 UHECR events with energies above 32 EeV. In this contribution, I present the search of this dataset for anisotropies on medium scales of a few tenths of degrees in the arrival directions of UHECRs. Evidence for an overdensity in the Centaurus region of the sky is obtained at the 4σ significance level, this evidence is corroborated by a catalog-based likelihood ratio analysis comparing the dataset against the distribution of the closest radiogalaxies and starburst galaxies.
