Supernovae RemnantsSupernova explosions have a very profound impact on the Interstellar Medium (ISM), both as sources of mechanical energy and heavy elements. Supernova Remnants (SNRs) provide information about these issues and can be observed as high-energy X-ray sources. The interaction of high velocity ejecta with the ISM generates very high temperatures, giving rise to line emission from heavy elements. By studying the spatial distribution of elements, one can gain insight into nucleosynthesis in the progenitor and the geometry of the explosions. SNRs are also possible sites of cosmic ray acceleration. [Ref 4] |
