| Abstract: |
Extensive Air Showers (EAS) reveal information about the highest energy
radiation in the Universe. HiRes images these EAS to harvest this
information and gain insight into the sources of these cosmic rays. The
measurement of the cosmic ray spectrum by HiRes, which led to the first
observation of the GZK cutoff, allows us to estimate fluxes of cosmogenic
neutrinos. HiRes data allows us to set limits on these neutrino fluxes.
I will discuss the current status of our quest for the sources of these
ultra high energy cosmic rays and the role of neutrinos in this context.
