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…

Atomic and molecular gas in the Milky Way. I. Structure decomposition

Xin Liu, Fujun Du

We present GDCluster, a fully automated algorithm for decomposing spectral-line datacube of interstellar gas into coherent structures. Assuming a multi-Gaussian nature of observed…

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…

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…

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…
