Abstract

The Very Large Array of the National Radio Astronomy Observatory in its B, C, and D configurations was used between July 1981 and August 1984 to clarify the morphology of several high-brightness sources from the Milne SNR catalog. Of these, the two sources G349.7+0.2 and G357.7-0.1 were found to be the most unusual. The former is the third brightest galactic SNR, after Cas A and the Crab Nebula. The source resembles shell-type remnants in some respects but lacks the usually prominent central cavity and ringlike appearance. G357.7-0.1 is the closest SNR to the galactic center direction and could be located in the nuclear disk itself. It has a relatively steep spectral index and is dissimilar in appearance to every other known SNR. The linear polarization, filaments, and three-dimensional structure of this object are discussed.
