Abstract

We present the results of new moderate resolution ATCA observations of SNR J0455-6838. We found that this SNR exhibits a mostly typical appearance with rather steep and curved α=-0.81±0.18 and D=43×31±1 pc. Regions of high polarization were detected, including unusually strong (~70%) region corresponding to the northern breakout. Such a strong polarization in breakout regions has not been observed in any other SNR.
