我们利用欧文斯河谷射电天文台的三元件毫米波干涉仪和加州理工大学亚毫米波天文台的10.4m望远镜，观测到了向SGR B2分子云核心的两个大质量恒星形成区--SGR B2(N)和(M)的1.3 mm连续谱和Hc3 N J=2 5→2 4辐射。干涉测量连续谱数据显示，在观测到的两个场中都存在致密尘埃源。北部连续谱源仅在N-S方向上分辨(去卷积的半高宽尺寸∼5“或0.2pC)
We have observed the 1.3 mm continuum and the HC 3 N J=25→24 emission toward two massive star-forming regions in the core of the Sgr B2 molecular cloud, Sgr B2(N) and (M), using the three-element millimeter-wave interferometer of the Owens Valley Radio Observatory and the 10.4 m telescope of the Caltech Submillimeter Observatory. The interferometric continuum data reveal the presence of compact dust sources in each of the two fields observed. The northern continuum source is only resolved in the N-S direction (deconvolved FWHM size ∼5″ or 0.2 pc)
