摘要
我们探测了朝向天体Circinus X-1（一个具有相对论性喷流的低质量X射线双星）和高度活跃的Westerlund 2星团（位于TeV伽马射线发射方向，且在Nanten 12CO数据中看到有趣的弧状和喷流状特征）的星际介质。我们用Mopra射电望远镜在7毫米和12毫米波段对这两个区域进行了成图，寻找高能外流与ISM相互作用导致的气体瓦解/致密的证据。朝向Westerlund 2，CS(J=1-0)发射峰值表明弧中部和喷流端点存在高密度气体；射电复合线发射与重合的HII区RCW49重叠。朝向Circinus X-1，Nanten 12CO(J=1-0)数据揭示了位于Cir X-1区域的三个分子云。给出了每个云的气体参数。
