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…
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…
Large-field CO(1-0) observations toward the Galactic historical supernova remnants: shocked molecular clouds toward the Crab Nebula
Xuepeng Chen, Dong Wang, Qianru He +4
Using the PMO 13.7m telescope, we present large-field and high-sensitivity CO(1-0) line observations toward the Crab Nebula, in order to better understand the interstellar gas envi…
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…
Multiple generation star formation in Cepheus Flare
Fan Wang, Min Fang, Xiaoting Fu +8
We present an analysis of the young stellar moving group ASCC 127 using Gaia DR3 data, significantly expanding its membership to 3,971 stars -- double the number identified in prev…
