Abstract content

The HiRes Experiment has observed the GZK Cutoff. We will present power law fits to the latest HiRes monocular spectra, and use the results of these fits to argue that the GZK Cutoff has been definitively observed in that dataset. We will also present fits to a uniform sorce density model.
