Scientific paper

The galactic supernova remnant G29.7-0.3, recently identified as a new member of the class of composite remnants, has been imaged with the VLA at three wavelengths: 2, 6, and 20 cm. Two spectrally distinct components, a flat-spectrum core surrounded by a shell with alpha of about -0.7, suggested by early observations, have been confirmed. Neutral hydrogen absorption measurements of these two components confirm their physical association and place the remnant at a distance of about 21 kpc. A radio polarization map of the Crab-like core and results of an examination of existing X-ray data for evidence of emission from the shell component are also presented. A comparison of the radio and X-ray properties of G29.7-0.3 and other composite SNRs concludes the report.
