Description
Using the recent Auger energy spectrum and composition
analysis results, an investigation is carried out into the requirements
placed on the UHECR sources. The spatial distribution of these
sources is investigated along with the energy distribution of UHECR
they output. These investigations reveal the need for local UHECR
sources which output a hard spectrum of intermediate/heavy UHECR.
These results demand that local (<80 Mpc) UHECR sources exist, placing
exciting and difficult requirements on the local extragalactic candidate
sources. None negligible (>0.01 nG) extragalactic magnetic fields are noted
to further strengthen these results
