- Description
- 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″ ×282″ ±4″ (90×68±1 pc), making it one of the largest known SNRs in the Local Group. We estimate a relatively steep radio spectral index of α = -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 [O III] and radio images, classifying this SNR as oxygen dominant.
