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,…

On gamma rays as predictors of UHECR flux in AGNs
Cainã de Oliveira, Rodrigo Guedes Lang, Pedro Batista
Active galactic nuclei (AGN) are among the main candidates for ultra-high-energy cosmic ray (UHECR) sources. However, while some theoretical and phenomenological works favor AGNs a…
