Radio Observations of Supernova Remnants
Supernovae release an enormous amount of energy into the interstellar medium. Their remnants can observationally be traced up to several ten-thousand years. So far more than 230 Galactic supernova remnants (SNRs) have been identified in the radio range. Detailed studies of the different types of SNRs give insight into the interaction of the blast wave with the interstellar medium. Shock acceler...
متن کاملX-ray Observations of Young Supernova Remnants
This brief review of recent X-ray observations of young supernova remnants highlights results obtained by the Chandra and XMM Newton Observatories since their launch last year. Their impressive capabilities are illustrated by results for spectral imaging, and for spatially resolved spectroscopy that isolates emission from individual ejecta knots and from the forward shock. I also review X-ray d...
متن کاملObservations of Supernova Remnants with VERITAS
The study of shell-type supernova remnants is a key science focus for the VERITAS TeV telescope array. Supernova remnants (SNRs) are widely considered to be the strongest candidate for the source of cosmic rays below the knee around 10 eV. This presentation will highlight new VERITAS results including new measurements of the spectra of Cas A and IC 443. These results and their implications for ...
متن کاملVisibility of Old Supernova Remnants in Hi 21 - cm
We estimate the number of old, radiative supernova remnants (SNRs) detectable in Hi 21-cm emission line in the Galaxy. We assume that old SNRs consist of expanding Hi shells and that they are visible if the line-of-sight velocities are sufficiently outside the velocity range of the Galactic background Hi emission. This criterion of visibility makes it possible to calculate the background contam...
متن کاملA Review of X-ray Observations of Supernova Remnants
Although radio and optical observations have played an important role in identifying and characterizing supernova remnants (SNRs), most of the shock heated material is primarily visible in X-rays, having temperatures of typically 10 − 10 K. The emission mechanisms are bremsstrahlung and line radiation, but a number of remnants are now known to emit Xray synchrotron radiation from ultra-relativi...
