Abstract

We present a new method to search for anisotropies in the arrival directions of ultra-high-energy-cosmic-rays (UHECR). The Cluster Algorithm method is derived from particle physics analyses for jet reconstruction. It aims at identifying a potential excess of small-scale clusters in the UHECR arrival directions with respect to an isotropic background. It is particularly sensitive to low statistics samples. The method can be applied either as a “catalogue-independent” one, or the resulting cluster positions can be compared to astronomical catalogues. Results based on different simulated source scenarios are presented.
