Abstract

We report the Australia Telescope Compact Array (ATCA) and ROSAT detection of supernova remnant (SNR) J0529âˆ’6653 in the Large Magellanic Cloud (LMC) which is positioned in the projected vicinity of the known radio pulsar PSR B0529âˆ’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 ÃƒÂ— 31 pc (1-pc uncertainty in each direction) and radio spectral index of Î±=âˆ’0.68 Ã‚Â± 0.03" typical for mid-age SNRs. We also report detection of polarized regions with a peak value of âˆ¼17 Ã‚Â± 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 SNR-pulsar association with emphasis on the large age difference, lack of a pulsar trail and no prominent point-like radio or X-ray source.
