Experimental constraints on the astrophysical interpretation of the cosmic ray Galactic-extragalactic transition region

C. De Donato, G. A. Medina-Tanco

The energy region spanning from $\sim 10^{17}$ to $\lesssim 10^{19}$ eV is critical for understanding both, the Galactic and the extragalactic cosmic ray fluxes. This is the region…
