The need for hard spectra sources of nearby heavy cosmic rays
Using recent Auger energy spectrum and composition analysis results, an investigation is carried out into the requirements placed on the UHECR sources. The the spatial distribution of these sources is investigated along with the energy distribution of UHECR they output. These investigations reveal t...
