| Abstract: |
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 implications 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. |
