Abstract

The Fleurs synthesis telescope has been used to map five radio sources believed to be supernova remnants. The high resolution of the radio maps has clearly delineated the source structures and has permitted useful comparisons with existing optical photographs. Two sources exhibit a shell structure and one of these contains a central point source which may prove to be the stellar remnant. Two sources resemble the Crab nebula (in that no enhanced shell is detectable). The remaining source has an arc structure but it is not yet clear whether it is truly a supernova remnant or a wide-angle head-tail galaxy.
