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…
Investigations of MWISP Bubbles: Identification and Analysis of Enclosed Molecular Bubbles by Weight Fields
Yu Jiang, Xuepeng Chen, Ji Yang +7
Molecular bubbles are widely used as tracers of stellar feedback; yet, their identification in spectral-line surveys remains challenging because both cavity morphology and kinemati…
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…
How is Cold Gas Loaded into Galactic Nuclear Outflows?
Yang Su, Xin Liu, Shiyu Zhang +7
The origin of the multiphase gas within the Fermi/eROSITA bubbles is crucial for understanding Galactic Center (GC) feedback. We use HI4PI data to investigate the kinematics and ph…
The Milky Way Imaging Scroll Painting Survey: Data Release 1
Ji Yang, Qing-Zeng Yan, Yang Su +31
We present the first data release (DR1) of the Milky Way Imaging Scroll Painting (MWISP) survey, a mapping in the J=(1-0) transition lines of 12CO, 13CO, and C18O toward the northe…
CU-JADE: A Method for Traversing Extinction Jumps along the Line of Sight
Shiyu Zhang, Yang Su, Xuepeng Chen +8
Although interstellar dust extinction serves as a powerful distance estimator, the solar system's location within the Galactic plane complicates distance determinations, especially…
