Probing for anisotropies at different angular scales in the arrival directions of the cosmic rays detected at the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +352
Studies of the arrival-direction distribution of ultra-high-energy cosmic rays are crucial for revealing their origin. In this work, we investigate the distribution of the arrival…

A search for sterile neutrinos at ultrahigh energies at the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +351
We investigate the sensitivity of the Pierre Auger Observatory to sterile neutrinos with masses in the MeV-to-100 MeV range. To this end, we consider a minimal framework in w…
