Abstract
We report the Australia Telescope Compact Array (ATCA) and ROSAT detection of supernova remnant (SNR) J0529-6653 in the Large Magellanic Cloud (LMC) which is positioned in the projected vicinity of the known radio pulsar PSR B0529-66. In the radio continuum frequencies, this LMC object follows a typical SNR structure of a shell morphology with brightened regions in the south-west. It exhibits an almost circular shape of D= 33 x 31 pc (1-pc uncertainty in each direction) and radio spectral index of a=-0.68 +/- 0.03 typical for mid-age SNRs. We also report detection of polarized regions with a peak value of similar to 17 +/- 7 per cent at 6 cm. An investigation of ROSAT images produced from merged Position Sensitive Proportional Counter (PSPC) data reveals the presence of extended X-ray emission coincident with the radio emission of the SNR. In X-rays, the brightest part is in the north-east. We discuss various scenarios with regard to the SNRpulsar association with emphasis on the large age difference, lack of a pulsar trail and no prominent point-like radio or X-ray source.
