摘要
This paper presents a high-resolution radio continuum (843 MHz) survey of the Vela supernova remnant. The contrast between the structures in the central pulsar-powered nebula of the remnant and the synchrotron radiation shell allows the remnant to be identified morphologically as a member of the composite class. The data are the first of a composite remnant at spatial scales comparable with those available for the Cygnus Loop and the Crab Nebula, and make possible a comparison of radio, optical, and soft X-ray emission from the resolved shell. filaments. The survey, made with the Molonglo Observatory Synthesis Telescope, covers an area of 50 deg(2) at a resolution of 43 " x 60 ", while imaging structures on scales up to 30'.
