来自超新星遗迹RX J0852.0-4622西北边缘的亚tev伽马射线发射是由CANGAROO II望远镜探测到的，最近得到了HESS小组的证实。此外，HESS数据还显示了一个非常宽（直径高达2°）的壳状伽马射线发射剖面。我们在2005年1月和2月用三台望远镜进行了CANGAROO III观测，这里展示了三倍巧合数据的结果。我们对HESS的形貌和能谱进行了验证，发现NW边缘的能谱与整个残余物的能谱一致。
Sub-TeV gamma-ray emission from the northwest rim of the supernova remnant RX J0852.0-4622 was detected with the CANGAROO II telescope and recently confirmed by the HESS group. In addition, the HESS data revealed a very wide (up to 2° in diameter), shell-like profile of the gamma-ray emission. We carried out CANGAROO III observations in 2005 January and February with three telescopes and show here the results of threefold coincidence data. We confirm the HESS results about the morphology and the energy spectrum and find that the energy spectrum in the NW rim is consistent with that of the whole remnant.
