Supernova Remnants as the Sources of Galactic Cosmic Rays
  The origin of cosmic rays holds still many mysteries hundred years after they
were first discovered. Supernova remnants have for long been the most likely
sources of Galactic cosmic rays. I discuss here some recent evidence that
suggests that supernova remnants can indeed efficiently accelerate cosmic rays.
For this conference devoted to the Astronomical Institute Utrecht I put the
emphasis on work that was done in my group, but placed in a broader context:
efficient cosmic-ray acceleration and the im- plications for cosmic-ray escape,
synchrotron radiation and the evidence for magnetic- field amplification,
potential X-ray synchrotron emission from cosmic-ray precursors, and I conclude
with the implications of cosmic-ray escape for a Type Ia remnant like Tycho and
a core-collapse remnant like Cas A.
