Description
Recent results from the Pierre Auger Observatory show that the
composition of ultra-high energy cosmic rays (UHECR) becomes
increasingly heavier on average with energy. We discuss potential
sources of UHECR in light of these results. In particular, we
detail on how some models of GRBs naturally predict UHECRs
that can even be dominate by very heavy nuclei beyond iron.
We also discuss potential signatures of nuclei UHECR.
