Molecular deuterations in massive Starless Clump Candidates
Kai Yang, Junzhi Wang, Keping Qiu +1
Deuterated molecules are valuable probes for investigating the evolution and the kinematics in the earliest stages of star formation. In this study, we conduct a comprehensive inve…
An improved method to measure and abundance ratios: revisiting CN isotopologues in the Galactic outer disk
Yichen Sun, Zhi-Yu Zhang, Junzhi Wang +7
The variations of elemental abundance and their ratios along the Galactocentric radius result from the chemical evolution of the Milky Way disks. The ratio in p…
Spatial distribution of NH2D in massive star-forming regions
Yuqiang Li, Junzhi Wang, Juan Li +4
To understand the relation between NHD and its physical environment, we mapped ortho-NHD at 85.9 GHz toward 24 Galactic late-stage massive star-forming…
Tentative detection of cyanoformamide NCCONH2 in space
Juan Li, Donghui Quan, Junzhi Wang +12
The peptide-like molecules, cyanoformamide (NCCONH2), is the cyano (CN) derivative of formamide (NH2CHO). It is known to play a role in the synthesis of nucleic acid precursors und…
Sulphur isotopes toward Sagittarius B2 extended envelope in the Galactic Center
Qingxu Li, Juan Li, Siqi Zheng +3
The isotopic ratios are good tools for probing the stellar nucleosynthesis and chemical evolution. We performed high-sensitivity mapping observations of the J=7-6 rotational transi…
Mapping Observations of Peptide-like molecules around Sagittarius B2
Siqi Zheng, Juan Li, Junzhi Wang +7
Peptide-like molecule, which has a close connection with the origin of life, has been detected in universe. Mapping observations of HCONH and CHCONH, two simplest pepti…
