Unmasking the ultrahigh-energy cosmic ray origin

Original language description

The sharp change in slope of the ultrahigh-energy cosmic ray spectrum around 109.6 GeV (the ankle), combined with evidence of a light but extragalactic component near and below the ankle which evolves to intermediate/heavy composition above, has proved exceedingly challenging to understand theoretically. Recently, we introduced a very general model in which, for a range of source conditions, photo-disintegration of ultrahigh-energy nuclei in the region surrounding the accelerator naturally accounts for the observed spectrum and composition of the entire extragalactic component, which dominates above about 108.5 GeV. In this communication we review the generalities of the model and show that starburst galaxies provide a compelling source example.
