Overview of Galactic Cosmic Rays, Status and Next Steps
With the first results from the new generation of TeV Cerenkov telescopes we again face the challenge of trying to understand the origin of Galactic cosmic rays. I will review the various conflicting arguments, and present some propagation calculations for the highest energy Galactic cosmic rays. It is likely that gamma ray observations will strongly constrain the possible sites of origin, but high precision spectra of secondary nuclei could do even more.
