NO molecule in massive star forming regions

Shaomin Su, Junzhi Wang, Rui Luo +7

Context. Among diatomic molecules composed of the abundant elements C, N and O, NO has been detected far less than the well studied CN and CO, making it a crucial yet under-observe…

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…

Dual-band Unified Exploration of Three CMZ Clouds (DUET). Cloud-wide census of continuum sources showing low spectral indices

Fengwei Xu, Xing Lu, Ke Wang +19

The Milky Way's Central Molecular Zone (CMZ) is measured to form stars 10 times less efficiently than in the Galactic disk, based on emission from high-mass stars. However, the CMZ…

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…

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$…

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…

OO abundance ratio toward a sample of massive star forming regions with parallax distances

Chao Ou, Junzhi Wang, Siqi Zheng +3

The OO abundance ratio is, in principle, a powerful tool to estimate the relative contributions of massive stars and low- to intermediate-mass stars to the chemical…

Imaging Molecular Outflow in Massive Star-forming Regions with HNCO Lines

Jinjin Xie, Juan Li, Junzhi Wang +8

Protostellar outflows are considered a signpost of star formation. These outflows can cause shocks in the molecular gas and are typically traced by the line wings of certain molecu…

Spatial distribution of HOCN around Sagittarius B2

Siqi Zheng, Juan Li, Junzhi Wang +4

HOCN and HNCO abundance ratio in molecular gas can tell us the information of their formation mechanism. We performed high-sensitivity mapping observations of HOCN, HNCO, and HNC$^…
