Single source scenario describing the very end of the cosmic ray energy spectrum

The energy spectrum of cosmic rays is steeply falling with a suppression the flux at highest energies caused by losses during propagation or reaching maximum accelerators. currently measured high precision two experiments, Telescope Array in Northern hemisphere and Pierre Auger Observatory Southern hemisphere. In this work, we study possibility explaining shape above 10 19.5 eV single source. Using CRPropa 3 numerical simulations ray Universe show possible features such source that would be able to create compatible measurement including limitations on distance, spectral index mass composition.
