The Search for the Sources of the Cosmic Rays One Century after their Discovery

Abstract

Despite their discovery potential touching a wide range of science, construction of TeV gamma-ray telescopes, Auger, IceCube and a suite of other particle astrophysics experiments has been largely motivated by the hunt for the sources of cosmic rays. I will assess the status of our search for the still-enigmatic sources of cosmic rays. Although a resolution is decidedly anticipated, the mystery of their origin remains unresolved.
