The origin(s) of Galactic cosmic ray nuclei remains a mystery even ~100
years after their first detection. The shock waves produced by
supernova remnants have long been favored as the sites where
cosmic ray nuclei gain their high energies, but proof of this
scenario has eluded observers for the past ~50 years. I will review
the current status of this problem with an emphasis of what
gamma-ray astronomy has and could tell us about where in the
Galaxy these energetic particles are accelerated.
Tuesday, March 4th at 4:00 p.m.
