Scientific paper

Although many supernova remnants are expected to interact with surrounding clouds, only IC 443 exhibits convincing evidence of such interactions, characterized by high perturbed gas with very large (equal to or greater than 20 km/s) velocity dispersions. Large scale, high resolution CO observations with the 14-m telescope of the Five College Radio Astronomy Observatory have revealed seven such regions, five newly discovered, in IC 443. A comparison with the IRAS Point Source Catalog shows that three bright, unidentified far-infrared point-like sources display good positional coincidence with clumps of highly perturbed gas. Chance superposition of the clumps and the IRAS sources is shown to be highly unlikely. It is suggested that the IRAS sources may delineate a new class of infrared objects associated with supernova remnants.
