Coevolution of Giant Molecular Cloud, Filaments and Clumps in relation to dense gas mass fraction

They selected 27 relatively isolated giant molecular clouds based on the CO data from the SEDIGISM survey (Schuller et al. 2017) and the COHRS survey (Dempsey et al. 2013) of the Milky Way. They used the dense gas mass fraction (DGMF) of...A research team led by Prof. ZHOU Jianjun, Prof. Jarken Esimbek and PhD student ZHANG Wenjun from the Xinjiang Astronomical Observatory of the Chinese Academy of Sciences, together with their collaborators, selected 27 relatively isolate...
