A new hot core in the outer Galaxy: Impact of metallicity on the formation of complex organic molecules
Youxin Wang, Arnaud Belloche, Robin T. Garrod
Many complex organic molecules (COMs) in star-forming regions are believed to form on dust grains. We thus expect both the reduced metallicity and dust-to-gas ratio in the outer Ga…

Sulfur monoxide as a tracer of the Galactic S/S gradient
Yipeng Zou, Jiangshui Zhang, Dingyuan Wei +6
To date, the Galactic interstellar radial S/S gradient has only been studied with the CS isotopologs, which may be affected by uncertainties due to the use of a singl…

Simulations for the evolution of the chemical clock HC3N/N2H+ in high-mass star-forming regions
Yao Wang, Fujun Du, Youxin Wang +2
From observations, column density ratios or integrated intensity ratios between some species exhibit monotonic increase or decrease along with the evolution of high-mass star-formi…
