摘要:

我们提出了新的澳大利亚望远镜紧凑阵列(ATCA)的观测结果的最大的超新星遗迹之一,SNR J 0450 -709,在本星系群。我们发现这个大麦云云(LMC)天体具有典型的老超新星遗迹(SNR)形态,直径D= 102 × 75 ± 1秒差距,射电光谱指数α =-0.43 ± 0.06。检测到高极化区域,峰值约为40%。

英文摘要:

We present the results of new Australia Telescope Compact Array (ATCA) observations of one of the largest supernova remnants, SNR J0450-709, in the Local Group of galaxies. We found that this Large Magellanic Cloud (LMC) ob ject exhibits a typical morphology of an old supernova remnant (SNR) with diameter D=102x75+-1 pc and radio spectral index alpha=-0.43+-0.06. Regions of high polarisation were detected with peak value of ~40%.
