Molecule-dependent Abundance Behavior of Oxygen-bearing Complex Organics in High-Mass Star-Forming Regions: A Uniform 50-source Survey
Xuefang Xu, Mingwei He, Qian Gou +10
We present a uniform IRAM-30\,m survey analysis of four oxygen-bearing complex organic molecules (COMs), methanol (CHOH), acetaldehyde (CHCHO), methyl formate (CHOCHO),…
The evolution of C4H and c-C3H2 in molecular cores
Yijia Liu, Junzhi Wang, Ningyu Tang +8
Linear C4H and cyclic c-C3H2, as small unsaturated hydrocarbons, are the key precursors to complex organic molecules and are critical components of the interstellar medium. We pres…
CH3CCH as a thermometer in warm molecular gas
Yuqiang Li, Junzhi Wang, Juan Li +9
Kinetic temperature is a fundamental parameter in molecular clouds. Symmetric top molecules, such as NH and CHCCH, are often used as thermometers. However, at high temperat…
Widespread Hot Molecular Gas Heated by Shear-induced Turbulence in the Galactic Center
Juan Li, Junzhi Wang, Zhiqiang Shen +13
We observed NH3 metastable inversion lines from (3, 3) to (18, 18) toward G0.66-0.13 in the Galactic center with the Shanghai Tianma 65m radio telescope and Yebes 40 m telescope. H…
NN abundance ratio toward massive star-forming regions with different Galactic distances
Chang Ruan, Junzhi Wang, Chao Ou +2
The abundance ratio of NN is, in principle, a powerful tool for tracing stellar nucleosynthesis. This work aims to measure and analyze (N/N)($^…
The deuterium fractionation of NH in massive star-forming regions
Yuqiang Li, Junzhi Wang, Juan Li +6
Deuteration is sensitive to environmental conditions in star-forming regions. To investigate NHD chemistry, we compared the spatial distribution of ortho-NHD $1_{11}^s-1_{0…
Spatial distribution of C4H and c-C3H2 in cold molecular cores
Yijia Liu, Junzhi Wang, Shu Liu +6
CH and -CH, as unsaturated hydrocarbon molecules, are important for forming large organic molecules in the interstellar medium. We present mapping observations of C$…
Dense Outflowing Molecular Gas in Massive Star-forming Regions
Yani Xu, Junzhi Wang, Shu Liu +6
Dense outflowing gas, traced by transitions of molecules with large dipole moment, is important for understanding mass loss and feedback of massive star formation. HCN 3-2 and HCO$…
The first Ka-band (26.1-35 GHz) blind line survey towards Orion KL
Xunchuan Liu, Tie Liu, Zhiqiang Shen +30
We conducted a Ka-band (26.1--35 GHz) line survey towards Orion KL using the TianMa 65-m Radio Telescope (TMRT). It is the first blind line survey in the Ka band, and achieves a se…
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…
Maser Investigation toward Off-Plane Stars (MIOPS): detection of SiO masers in the Galactic thick disk and halo
Wenjin Yang, Yuanwei Wu, Yan Gong +7
Studying stars that are located off the Galactic plane is important for understanding the formation history of the Milky Way. We searched for SiO masers toward off-plane O-rich asy…
