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…
A large-scale foundation model enables simulation-to-real adaptation for nuclear magnetic resonance-based molecular structure analysis
Chen Yang, Zheng Fang, Hanyu Sun +7
Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful tool for molecular structure analysis, and spectral artificial intelligence offers great potential for its rapid and aut…
The gas kinematics in 70 μm dark molecular clumps with ammonia
Chao Ou, Shanghuo Li, Junzhi Wang +5
We present the investigation of the gas kinematics and assess the evolutionary stages of dense cores embedded in four infrared dark clouds (IRDCs) using the NH(1,1) and NH(…
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…
