CO Structures with Narrow Lines in Nearby Quiescent Regions
Ruilin Xia, Yang Su, Shiyu Zhang +13
Using CO data from Phase I of the Milky Way Imaging Scroll Painting (MWISP) survey, we present a systematic study of molecular structures with narrow lines. We identify 57 CO struc…
Statistical Properties of Molecular Clouds in the Milky Way: Insights from Three-Isotopologue CO Observations of the MWISP Project
Xin Zhou, Ji Yang, Qing-Zeng Yan +5
We present a comprehensive statistical analysis of molecular cloud (MC) properties using the MWISP survey's 12CO, 13CO, and C18O (J = 1--0) data toward the inner (l = 45--6…
PMO Polaris CO survey. II. Where is the dust?
Xunchuan Liu, Bing Gang Ju, Fujun Du +10
Dust plays critical chemical and dynamical roles in the interstellar medium (ISM), but its specific association with molecular and atomic gas remains difficult to isolate. Combinin…
PMO Polaris CO survey. I. A 100 deg view of the Polaris Flare
Xunchuan Liu, Bing-Gang Ju, Fujun Du +10
Large-area CO surveys are essential for studying molecular cloud dynamics and evolution; however, most have focused on the Galactic plane, leaving high-latitude clouds less explore…
A study of the Physical Properties and Star Formation Activity of a Large Sample of Molecular Clouds: I Distances
Juan Mei, Min Fang, Miaomiao Zhang +8
Accurate distances to molecular clouds are crucial for determining their physical properties, understanding star formation, and tracing Galactic spiral structure. A number of 103,5…
The radial velocity stability for reference sources in the MWISP CO survey
Lixia Yuan, Ji Yang, Min Fang +3
To assess the velocity stability of CO spectral lines in the Milky Way Imaging Scroll Painting (MWISP) survey, we employ a cross-correlation method to measure velocity shifts acros…
