A New Statistical Analysis of the Morphology of Spiral Galaxies
Junye Wei, Ye Xu, Zehao Lin +4
Morphology is the starting point for understanding galaxies. Elmegreen et al. classified spiral galaxies into flocculent, multiple-arm, and grand-design galaxies based on the regul…

Yiwei Dong, Ye Xu, Chaojie Hao +4
The Canis Major (CMa) region is known for its prominent arc-shaped morphology, visible at multiple wavelengths. This study integrates molecular gas data with high-precision astrome…
VLBI with SKA: Possible Arrays and Astrometric Science
Yingjie Li, Ye Xu, Jingjing Li +4
The next generation of very long baseline interferometry (VLBI) is stepping into the era of microarcsecond (as) astronomy, and pushing astronomy, especially astrometry, to new h…
Probing the nature of rotation in the Pleiades, Alpha Persei, and Hyades clusters
C. J. Hao, Y. Xu, L. G. Hou +5
Unraveling the internal kinematics of open clusters is crucial for understanding their formation and evolution. However, there is a dearth of research on this topic, primarily due…
Molecular Bubble and Outflow in S Mon Revealed by Multiband Datasets
Dejian Liu, Ye Xu, YingJie Li +8
We identify a molecular bubble, and study the star formation and its feedback in the S Mon region, using multiple molecular lines, young stellar objects (YSOs), and infrared data.…
Kinematics of the Local Spiral Structure Revealed by Young Stars in \emph{Gaia}~DR3
Dejian Liu, Ye Xu, Chaojie Hao +4
Using young open clusters and O--B2-type stars in~\emph{Gaia}~DR3, we investigate the kinematics of the local spiral structure. In general, the young sources in the outer spiral ar…

Yiwei Dong, Yan Sun, Ye Xu +11
We present the results of an unbiased CO/CO/CO ( = 1-0) survey in a portion of the third Galactic quadrant (TGQ): = [219.75, 229.75] and = […
Unveiling the initial conditions of open star cluster formation
C. J. Hao, Y. Xu, L. G. Hou +2
Open clusters (OCs) are infrequent survivors of embedded clusters gestated in molecular clouds. Up to now, little is known about the initial conditions for the formation of OCs. He…
What Does the Milky Way Look Like?
Y. Xu, C. J. Hao, D. J. Liu +5
In spite of much work, the overall spiral structure morphology of the Milky Way remains somewhat uncertain. In the last two decades, accurate distance measurements have provided us…
On the nature of rotation in the Praesepe cluster
C. J. Hao, Y. Xu, S. B. Bian +4
Although a large number of Galactic open clusters (OCs) have been identified, the internal kinematic properties (e.g., rotation) of almost all the known OCs are still far from clea…
