Radio-continuum study of MCSNR J0536-7038 (DEM L249)

We present a detailed radio-continuum study on Australia Telescope Compact Array (ATCA) observations of Large Magellanic Cloud (LMC) supernova remnant (SNR), MCSNR J0536-7038. This Type Ia SNR follows a horseshoe morphology, with a size 32 pc $\times$ 32 pc (1-pc uncertainty in each direction). It exhibits a radio spectrum $\alpha=-0.52\pm0.07$ between $\lambda = 73$ and 6 cm. We report detections of regions showing moderately high fractional polarisation at 6 cm, with a peak value of 71$\pm$25% and a mean fractional polarisation of 35$\pm$8%. We also estimate an average rotation measure across the remnant of -237 rad m$^{-2}$. The intrinsic magnetic field appears to be uniformly distributed, extending in the direction of the two brightened limbs of the remnant.
