A Detailed Comparison of X-ray and Radio Structure of the Cygnus Loop

The Cygnus Loop is one of the largest and nearest supernova remnants. It has been mapped by the PSPC detector of the Rontgen-Satellit ROSAT (Aschenbach and Leahy, 1999) resulting in the highest-sensitivity complete x-ray image of this remnant. The radio structure of the Cygnus Loop was observed at 1420 MHz with the synthesis telescope of the Dominion Radio Astrophysical Observatory (Leahy, Roger and Ballantyne, 1997) with similar spatial resolution. Here, is reported on a detailed comparison of the structure of the Cygnus Loop in x rays and radio.
