Query: Cosmic rays from supernova remnants and superbubbles   Recent high energy gamma-ray observations of both single supernova remnants
and superbubbles, together with observations of supernovae, star formation
regions, and local cosmic ray composition, now provide an integrated framework
tying together the sources, injection, acceleration and propagation of the
cosmic rays, so that it is possible to determine their relative contributions
to cosmic ray acceleration for all but the very highest energies.
