High-Priority Compact-Object Candidates in Young Clusters from the \textit{Gaia} DR3 Non-Single-Star Catalog
Dejian Liu, Kangteng Chang, Yao Huang +7
The search for massive compact objects such as black holes (BHs) or neutron stars (NSs) in star clusters is longstanding challenge in astrophysics, yet no definitive identification…
Morphological Statistic of Milky Way-like Galaxies
Zehao Lin, Junye Wei, Ye Xu +5
We analyze the spiral morphology of 1,738 nearby galaxies with similar Hubble type of the Milky Way (, ) using multi-band optical images from the Sloan Digital…
Star Formation in the H II Region Sh 2-205: 3D Morphology and Kinematics from Young Stars and Molecular Gas
Yiwei Dong, Chaojie Hao, Ye Xu +5
Using Gaia astrometry of young stars combined with CO observations, we present the first systematic three-dimensional (3D) analysis of the structure, kinematics, and evolutionary h…
Mapping the Milky Way with Masers
Ye Xu, Kazi Rygl, Huib Jan van Langevelde +10
SKA-VLBI is poised to revolutionize our understanding of the Galactic structure through its unprecedented astrometric precision and sensitivity. As a next-generation facility, it w…
Outflowing Gas in the Planetary Nebula K 3-54
Xiuhui Chen, Dejian Liu, Ping Yan +3
As planetary nebulae (PNe) evolve, they develop slow and strong dust-driven stellar winds, making the joint study of dust and gas essential for understanding their nature. As a pil…
Kinematics of Young Stellar Objects Under Various Stellar Feedback
Longhui Yang, Dejian Liu, Chaojie Hao +6
Based on the Gaia Data Release 3 and APOGEE datasets, we investigate the kinematic differences between young stellar objects (YSOs) and their parent clouds in five nearby star-form…
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…
3D Morphology and Motions of the Canis Major Region from Gaia DR3
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…
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…
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…
Neutral Stellar Winds Toward the High-Mass Star-Forming Region G176.51+00.20
Li Yingjie, Xu Ye, Xu Jin-Long +7
We observed the high-mass star-forming region G176.51+00.20 using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) with the 19-beam tracking observational mode. Thi…
HI Narrow-Line Self-Absorptions Toward the High-Mass Star-Forming Region G176.51+00.20
Li Yingjie, Xu Ye, Xu Jin-Long +7
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) 19-beam tracking observational mode, high sensitivity and high-velocity resolution HI spectral lines have bee…
High-sensitivity millimeter imaging of molecular outflows in nine nearby high-mass star-forming regions
De-Jian Liu, Ye Xu, Ying-Jie Li +6
We present a study of molecular outflows using six molecular lines (including 12CO/13CO/C18O/HCO+(J = 1-0) and SiO/CS(J = 2-1)) toward nine nearby high-mass star-forming regions wi…
