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…
