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…

Examining Turbulence in Galactic Molecular Clouds - II: Continuity of Turbulence Cascading in a Portion of the Local Arm

Yuehui Ma, Miaomiao Zhang, Hongchi Wang +5

We use CO (J=1-0) MWISP data to study turbulence in a segment of the Local Arm. Velocity slices at different kinematic distances show similar spatial power spectra (SPSs) an…

Hierarchical Structure and Self-gravity in the Rosette Molecular Cloud

Suziye He, Yuehui Ma, Hongchi Wang +6

We analyze the hierarchical structure in the Rosette Molecular Cloud (RMC) using CO J=1-0 data from the Milky Way Imaging Scroll Painting (MWISP) survey with a non-binary De…

Simulations for the evolution of the chemical clock HC3N/N2H+ in high-mass star-forming regions

Yao Wang, Fujun Du, Youxin Wang +2

From observations, column density ratios or integrated intensity ratios between some species exhibit monotonic increase or decrease along with the evolution of high-mass star-formi…

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…

Dust processing in the terrestrial planet-forming region of the PDS 70 disk

Yao Liu, Dafa Li, Hongchi Wang +5

Dust grains in protoplanetary disks are the building blocks of planets. Investigating the dust composition and size, and their variation over time, is crucial for understanding the…
