Radio continuum observations of LMC SNR J0550-6823
  We report on new Australia Telescope Compact Array (ATCA) observations of the
Large Magellanic Cloud (LMC) supernova remnant (SNR) J0550-6823 (DEM L328).
This object is a typical horseshoe SNR with a diameter of 373" x 282" +- 4" (90
x 68 +- 1), making it one of the largest known SNRs in the Local Group. We
estimate a relatively steep radio spectral index of alpha = -0.79 +- 0.27.
However, its stronger than expected polarisation of 50% +- 10% is atypical for
older and more evolved SNRs. We also note a strong correlation between [Oiii]
and radio images, classifying this SNR as oxygen dominant.
