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 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…
Gas Transfer Between the Inner 3-kpc Disk and the Galactic Central Molecular Zone
Yang Su, Shiyu Zhang, Yan Sun +10
We uncovered a more tilted molecular gas structure with highly negative velocities located near the dust lane. Our observations also show that the approaching gas flows from the ov…
A Study of Multiple Molecular Lines at the 3 mm Band toward Gas Infalling Sources
Yang Yang, Xi Chen, ZhiBo Jiang +3
The study of multiple molecular spectral lines in gas infalling sources can provide the physical and chemical properties of these sources and help us estimate their evolutionary st…
Examining Turbulence in Galactic Molecular Clouds -- I: A Statistical Analysis of Velocity Structures
Yuehui Ma, Miaomiao Zhang, Hongchi Wang +14
We present a systematic analysis of the velocity structure functions (VSFs) of 167 molecular clouds with angular sizes greater than 176 arcmin in three sectors of the Gal…
