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…
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…
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…
Dust extinction map of the Galactic plane based on the UKIDSS survey data
Miaomiao Zhang, Jouni Kainulainen, He Zhao +5
Dust plays a critical role in the study of the interstellar medium (ISM). Extinction maps derived from optical surveys often fail to capture regions with high column density due to…
