Observation of the Moon and Sun shadows with cosmic rays at an average energy of eV
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +346
Interactions of cosmic rays with the Moon and the Sun produce deficits in their arrival-direction distributions relative to an isotropic flux. Such shadows have been observed previ…
Search for ultra-high energy neutrons from Galactic sources with the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +357
Deflections in the propagation of charged ultra-high-energy cosmic rays (UHECRs) caused by magnetic fields make the identification of their sources challenging. On the other hand,…
