Ultra High Energy Cosmic Rays versus Models of High Energy Hadronic Interactions
Blaž Bortolato, Jernej F. Kamenik, Michele Tammaro
We evaluate the consistency of hadronic interaction models in the CORSIKA simulation package with publicly available fluorescence telescope data from the Pierre Auger Observatory.…

Resolution of (Heavy) Primaries in Ultra High Energy Cosmic Rays
Blaž Bortolato, Jernej F. Kamenik, Michele Tammaro
Measurements of Ultra-High Energy Cosmic Rays (UHECR) suggest a complex composition with significant contributions from heavy nuclei at the highest energies. We systematically expl…

Learning the Composition of Ultra High Energy Cosmic Rays
Blaz Bortolato, Jernej F. Kamenik, Michele Tammaro
We apply statistical inference on the Pierre Auger Open Data to discern for the first time the full mass composition of cosmic rays at different energies. Working with longitudinal…
