The Physics of UHECRs: Spectra, Composition and the Transition Galactic-Extragalactic
arXiv:1704.07110 · doi:10.7566/JPSCP.19.011008
Abstract
We review the experimental evidences about flux and mass composition of ultra high energy cosmic rays in connection with theoretical scenarios concerning astrophysical sources. In this context, we also address the discussion about the expected transition between cosmic rays produced inside the Galaxy and those coming from the intergalactic space.
