摘要
We present new radio images, including the highest resolution image obtained to date, of the known oxygen-rich supernova remnant 1E 0102.2 7219 in the Small Magellanic Cloud. These images, made with the Molonglo Observatory Synthesis Telescope (44'' resolution) and the Australia Telescope Compact Array (3'' resolution), reveal an almost complete shell of radio emission and a spectral index of approximately - 0.7. The images also clearly show a previously unidentified compact component. The radio images are compared with previously published optical emission line and X-rav images, and the identification of the diameter of the super-nova blast wave is briefly discussed.
