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,…
A 6.7 GHz Methanol Maser Survey at High Galactic Latitudes
Kai Yang, Xi Chen, Zhi-Qiang Shen +8
We performed a systematic 6.7 GHz Class \uppercase\expandafter{\romannumeral2} methanol maser survey using the Shanghai Tianma Radio Telescope toward targets selected from the all-…
Astrophysical constraints on the proton-to-electron mass ratio with FAST
Xi Chen, Simon P. Ellingsen, Ying Mei
That the laws of physics are the same at all times and places throughout the Universe is one of the basic assumptions of physics. Astronomical observations provide the only means t…
