IC 443 is the best known example of a supernova shock running into a molecular cloud complex. This can be seen from the line profiles, which are broad due to the shock. The morphology of this source is a tilted ring of molecular material compressed by the shock. There are also a couple of individual clouds present, that are not part of the ring structure.
A picture of this source is here. It is a IRAS 100 micron image, created by the IRAS server in Groningen. A high resolution image is also available. This image was obtained using the maximum entropy method HIRAS.
This is work I do together with Ewine F. van Dishoeck (my thesis supervisor) in Leiden, John Black in Tucson, Arizona (for the modeling) and Tom Phillips at Caltech / Caltech Submillimeter Observatory (for the observational part).
