The Epoch of the GSE Merger: Insights from the Splash and Thick Disk Age Distributions
Sihan Lu, Yang Huang, Qikang Feng +1
The epoch of the Gaia-Sausage-Enceladus (GSE) merger, the last major merger experienced by the Milky Way, is crucial for reconstructing the Galaxy's evolutionary history. This even…
An Old, Low-mass, Metal-poor Hypervelocity Star Candidate Consistent with a Galactic Center Origin
Shunhong Deng, Yang Huang, Haozhu Fu +4
We report the discovery of DESI-HVS1, a hypervelocity star (HVS) candidate identified from DESI DR1 spectroscopy and Gaia DR3 astrometry. DESI-HVS1 is an old, low-mass, metal-poor…
The Fate of the Milky Way--Andromeda System: To Merge or Not?
Hao Wu, Yang Huang, Huawei Zhang +2
It has long been predicted that the Milky Way (MW) will eventually merge with Andromeda (M31), a view reinforced by \textit{HST} measurements indicating a small M31 transverse velo…
The rotation curve of the Milky Way measured by Classical Cepheids from Gaia DR3
Qikang Feng, Yang Huang, Huawei Zhang +1
We determine the rotation curve (RC) of the Milky Way in the range 6 < R < 18 kpc using a sample of 903 carefully selected classical Cepheids with precise proper motions and high-q…
A 3D Chemodynamical Census of Inner-Galaxy Metal-poor Giants to [Fe/H]~-3.5
Shenglan Sun, Yang Huang, Fangzhou Jiang +8
The earliest assembly of the Milky Way remains poorly understood, yet the spatial, chemical, and kinematic properties of its most metal-poor stars provide a unique fossil record of…
Search for Distant Hypervelocity Star Candidates Using RR Lyrae Stars
Haozhu Fu, Yang Huang, Huawei Zhang
Hypervelocity stars (HVSs) are stars with velocities exceeding their local escape velocities. Searching for HVSs and studying their origins can be an important way to study the pro…
