Scientific rationale

Supernova remnants (SNRs) are the most energetic objects in the Galactic disk, and have been observed at various wavelengths from radio to gamma-rays. One of the most spectacular features of SNRs is the fast moving expanding shells whose velocity is measured ~3000-5000 km/s. Recent observations of the shells in X-rays as well as radio continuum emission have provided a wealth of information on their physical/kinematical properties. It is also remarkable that the dense interstellar medium interacting with the shells is likely playing a key role to produce X- and gamma-rays as shown by comparisons with HI/CO and dust emission. Theoretical works on cosmic-ray acceleration/escaping in SNRs are unveiling details of cosmic-ray acceleration/propagation by magneto-hydro-dynamical numerical simulations which will be compared with observations. In this workshop, we invite observers and theorists in order to stimulate active interaction and exchange of ideas on SNRs.
