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…
RV and TTV Measurements of Two Transiting Long-Period Giants around TOI-4600
Tong Hu, Zitao Lin, Sharon X. Wang +27
TOI-4600b and c, originally identified by the Transiting Exoplanet Survey Satellite (TESS) and reported by I. Mireles et al. (2023), are a rare pair of transiting long-period giant…
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…
Revisiting the Proper Motions of M31 and M33 Using Massive Supergiant Stars with Gaia DR3
Hao Wu, Yang Huang, Huawei Zhang +1
The proper motions (PMs) of M31 and M33 are key to understanding the Local Group's dynamical evolution. However, measurement discrepancies between Gaia blue and red samples, regard…
