UHECR Phenomenology – Glennys Farrar

I will review some very general properties that must characterize any relativistic UHECR accelerator, and I will list some key observational constraints on the accelerators. In combination these make it unlikely that any of the conventional source candidates can be solely responsible for the observed cosmic rays about about 60 EeV. I will describe a recently proposed new mechanism that is in excellent accord with the constraints and observations. I will describe how it can be tested using UHECRs and GLAST.
