A Low-mass Model of The Milky Way: The Disk Warp Resulting from A Galaxy Merger
Mingji Deng, Cuihua Du, Jian Zhang +2
Previous studies have shown that disk warps can result from galaxy mergers. Recent research indicates a noticeable decline in the rotation curve (RC) of the Milky Way (MW), suggest…

Kinematic, Elemental and Structural Dependences on Metallicity in the Galactic Bulge
Haoyang Liu, Cuihua Du, Zhongcheng Li +2
We selected Bulge stars from APOGEE DR17 cross-matched with astrometric data from \textit{Gaia} DR3. Bulge stars were divided into sub-samples with line-of-sight velocity dispersio…

Investigate Substructures of the Inner Halo Using the StarGO Algorithm with APOGEE DR17
Zhongcheng Li, Cuihua Du, Haoyang Liu +1
We applied Stars' Galactic Origin (StarGO) algorithm in 7D space (i.e., [Fe/H], [Mg/Fe], [Al/Fe], , , , ) to analyze stars in the inner halo with APOGEE DR1…
