Abstract

ray (ATCA) observations of supernova remnant, SNR J0536–6735. This remnant appears to follow a shell morphology with a diameter of D=36×29 pc (with 1 pc un-certainty in each direction). There is an embedded H ii region on the northern limb of the remnant which made various analysis and measurements (such as flux density, spectral index and polarisation) difficult. The radio-continuum emission followed the same structure as the optical emission, allowing for extent and flux density esti-mates at 20 cm. We estimate the surface brightness at 1 GHz of 2.55×10−21 Wm−2 Hz−1 sr−1 for the SNR. Also, we detect a distinctive radio-continuum point source which confirms the previous suggestion of this remnant being associated with pulsar wind nebula (PWN). The tail of this remnant is not seen in the radio-continuum images and is only seen in the optical and X-ray images.
