High resolution radio observations of the composite supernova remnant (SNR)G326.3-1.8 or MSH 15-56 with the Australia Telescope Compact Array show detailsof both the shell and the bright plerion which is offset about 1/3 of thedistance from the center of the SNR to the shell. The shell appears to becomposed of thin filaments, typical of older shell SNRs. The central part ofthe elongated plerion is composed of a bundle of parallel ridges which bulgeout at the ends and form a distinct ring structure on the northwestern end. Themagnetic field with a strength of order 45 microGauss, is directed along theaxis of the ridges but circles around the northwestern ring. This plerion islarge and bright in the radio but is not detected in x-ray or opticalwavelengths. There is, however, a faint hard x-ray feature closer to the shelloutside the plerion. Perhaps if the supernova explosion left a rapidly movingmagnetar with large energy input but initially rapid decay of both relativisticparticles and magnetic field, the observed differences with wavelength could beexplained.Comment: 15 pages, 10 figures, accepted by Ap
