Investigating the vertical distribution of the disk as a function of radial action: Results from simulations

Yunpeng Jia, Chengqun Yang, Yuqin Chen +2

Previous research has established a relationship between radial action and scale height in Galactic disks, unveiling a correlation between radial and vertical heating. This finding…

The origin of High-velocity stars considering the impact of the Large Magellanic Cloud

Jiwei Liao, Cuihua Du, Mingji Deng +5

Utilizing astrometric parameters sourced from \textit{Gaia} Data Release 3 and radial velocities obtained from various spectroscopic surveys, we identify 519 high-velocity stars (H…

Dynamical substructures of local metal-poor halo

Dashuang Ye, Cuihua Du, Jianrong Shi +1

Based on 4,\,098 very metal-poor (VMP) stars with 6D phase-space and chemical information from \textit{Gaia} DR3 and LAMOST DR9 as tracers, we apply an unsupervised machine learnin…

Discovery of the shell structure via break radii in the outer halo of the Milky Way

Dashuang Ye, Cuihua Du, Jianrong Shi +1

Based on the \textit{Gaia} DR3 RR Lyrae catalog, we use two methods to fit the density profiles with an improved broken power law, and find that there are two break radii coincidin…

Investigating the vertical distribution of the disk as a function of radial action

Yunpeng Jia, Yuqin Chen, Cuihua Du +1

As heating processes can broaden the distributions of radial actions and the vertical distributions of the Galactic disks, we investigate the vertical distribution of the Galactic…

60 candidate high-velocity stars originating from the Sagittarius dwarf spheroidal galaxy in Gaia EDR3

Hefan Li, Cuihua Du, Jun Ma +3

Using proper motions from Gaia Early Data Release 3 (Gaia EDR 3) and radial velocities from several surveys, we identify 60 candidate high-velocity stars with total velocity greate…
