From local chemistry to galactic evolution: unlocking the power of interstellar isotopes with ALMA2040
Laura Colzi, Hayley A. Bunn, Víctor M. Rivilla +29
Molecular isotopic ratios provide a unique window into the chemical evolution of the interstellar medium, linking stellar nucleosynthesis and Galactic chemical evolution to the phy…
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…
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…
