UHECRs Propagation and their Multimessengers: Upper limits and the Impact of the Extragalactic Magnetic Field
Rodrigo Sasse, Rubens Costa, Adriel G. B Mocellin +2
The detection of high-energy astrophysical multimessengers establishes a connection between ultra-high-energy cosmic rays (UHECRs) and powerful cosmic accelerators. Interactions of…
