We present the analysis of cloud-cloud collision (CCC) process in the Galactic molecular complex S235. Our new CO observations performed with the PMO-13.7m telescope reveal two mol…
CO-CHANGES I: IRAM 30m CO Observations of Molecular Gas in the Sombrero Galaxy
Yan Jiang, Jiang-Tao Li, Yu Gao +7
Molecular gas plays a critical role in explaining the quiescence of star formation (SF) in massive isolated spiral galaxies, which could be a result of either the low molecular gas…
Discovery of Carbon Monoxide in Distant Comet C/2017 K2 (PANSTARRS)
Bin Yang, David Jewitt, Yuhui Zhao +3
Optical observations of the Oort cloud comet C/2017 K2 (PANSTARRS) show that its activity began at large heliocentric distances (up to 35 au), which cannot be explained by either t…
VALES VII: Molecular and ionized gas properties in pressure balanced interstellar medium of starburst galaxies at z ~ 0.15
