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…
