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…
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…
East Asian VLBI Network astrometry toward the star-forming region G040.96+02.48 in the Extreme Outer Galaxy
Xianjin Shen, Zehao Lin, Nobuyuki Sakai +18
Accurate astrometric measurements for star-forming regions located on the far side of the Milky Way remain scarce. In this work, we present the astrometric results for a 22\,GHz wa…
Discovery of a high-velocity cloud of the Milky Way as a potential dark galaxy
Xiao-Lan Liu, Jin-Long Xu, Peng Jiang +6
High-velocity clouds (HVCs) are composed of neutral hydrogen (HI) moving at velocities that deviate from the general rotational motion of the Milky Way. Currently, the origins of t…
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…
Search for Classical Cepheids in Galactic Open Clusters and Calibration of the Period Wesenheit Metallicity Relation in the Gaia Bands
Huajian Wang, Ye Xu, Zehao Lin +3
It is beneficial to calibrate the period Wesenheit metallicity relation (PWZR) of Delta Cephei stars (DCEPs), i.e., classical Cepheids, using accurate parallaxes of associated open…
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.…
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…
