| Abstract: | Supernova remnants are beautiful astronomical objects that are also of high scientific interest, because they provide insights
into supernova explosion mechanisms, and because they are the likely sources of Galactic cosmic rays. X-ray observations are
an important means to study these objects. And in particular the advances made in X-ray imaging spectroscopy over the last
two decades has greatly increased our knowledge about supernova remnants. It has made it possible to map the products of fresh
nucleosynthesis, and resulted in the identification of regions near shock fronts that emit X-ray synchrotron radiation. Since
X-ray synchrotron radiation requires 10–100 TeV electrons, which lose their energies rapidly, the study of X-ray synchrotron
radiation has revealed those regions where active and rapid particle acceleration is taking place. |
