Neutral iron line in the supernova remnant IC 443 and implications for MeV cosmic rays

We report a discovery of bright blob-like enhancements of an Fe i K$\alpha$ line in the northwest and the middle of the supernova remnant (SNR) IC 443. The distribution of the line emission is associated with molecular clouds interacting with the shock front, and is totally different from that of th...
