Mapping Observations of complex organic molecules around Sagittarius B2 with ARO 12m telescope
Juan Li, Junzhi Wang, Haihua Qiao +10
We performed high-sensitivity mapping observations of several complex organic molecules around Sagittarius B2 with ARO 12m telescope at 3-mm wavelength. Based on their spatial dist…
Determining electron temperature and density in a H II region by using the relative strengths of hydrogen radio recombination lines
F. -Y. Zhu, Q. -F. Zhu, J. -Z. Wang +1
We have introduced a new method of estimating the electron temperature and density of H II regions by using single dish observations. In this method, multiple hydrogen radio recomb…
Formation of Massive Protostellar Clusters -- Observations of Massive 70 m Dark Molecular Clouds
Shanghuo Li, Qizhou Zhang, Thushara Pillai +3
We present Submillimeter Array (SMA) observations of seven massive molecular clumps which are dark in the far-infrared for wavelengths up to 70 m. Our 1.3 mm continuum images re…
A 6.7 GHz Methanol Maser Survey II. Low Galactic Latitudes
Kai Yang, Xi Chen, Zhi-Qiang Shen +7
We report the results of our systematic survey for Galactic 6.7 GHz Class II CHOH maser emission toward a sample of young stellar objects. The survey was conducted with the Sha…
Carbon-Chain Molecules in Molecular Outflows and Lupus I Region--New Producing Region and New Forming Mechanism
Yuefang Wu, Xunchuan Liu, Xi Chen +18
Using the new equipment of the Shanghai Tian Ma Radio Telescope, we have searched for carbon-chain molecules (CCMs) towards five outflow sources and six Lupus I starless dust cores…
A particular carbon-chain-producing region: L1489 starless core
Yuefang Wu, Lianghao Lin, Xunchuan Liu +14
We detected carbon-chain molecules (CCMs) HC2n+1N (n=1-3) and C3S in Ku band as well as {high-energy excitation lines including C4H N=9-8, J=17/2-15/2, 19/2-17/2, and CH3CCH J=5-4,…
