A -like metallicity profile in the disk of the Sagittarius dwarf galaxy

Zixi Guo, Xiang-Xiang Xue, Jiang Chang +12

Unveiling the properties of the progenitors that formed the tidal structures of the Milky Way (MW) is essential for exploring the MW's assembly history. Such studies further afford…

Galactic Stellar Halo Luminosity Function

Sarah A. Bird, Chris Flynn, Rudra Sekhri +5

We measure the luminosity function (LF) of the Milky Way's stellar halo, using a magnitude complete, distance limited sample of stars from DR3. Stars with high transverse ve…

The binary fraction of Blue Horizontal-Branch (BHB) Stars

Yanjun Guo, Kun Chen, Zhenwei Li +6

Blue horizontal-branch (BHB) stars are old, low-mass, metal-poor stars that serve as important tracers of the Galactic halo structure, kinematics, and evolution.Understanding their…

ViT-based Local Volume dwarf galaxy Identificationin (VIDA) in the CSST survey

Han Qu, Zhen Yuan, Chengliang Wei +11

Identifying dwarf galaxies within the Local Volume is crucial for constraining the luminosity function of satellite galaxies in the nearby universe. We report the detection capabil…

The Shape and Mass of the Galactic Dark Matter Halo from the Axisymmetric Jeans Model

Lan Zhang, Xiang-Xiang Xue, Ling Zhu +8

We explore the density profile, shape, and virial mass of the Milky Way's dark matter halo using K giants (KG) from LAMOST and SDSS/SEGUE, as well as blue horizontal branch (BHB) s…

Identification of a dwarf galaxy stream in Gaia, and its possible association with the VPOS structure

Hao Tian, Chao Liu, Xiang-Xiang Xue +6

Low surface density streams are important tracers to study the formation and evolution of the Milky Way. Using the accurate astrometric measurements from Gaia mission, we discover…

A New Tidal Stream Discovered in Gaia DR3

Hao Tian, Chao Liu, Changqing Luo +2

Thanks to the precise astrometric measurements of proper motions by the Gaia mission, a new tidal stellar stream has been discovered in the northern hemisphere. The distribution of…

Uncovering the first-infall history of the LMC through its dynamical impact in the Milky Way halo

Yanjun Sheng, Yuan-Sen Ting, Xiang-Xiang Xue +2

The gravitational interactions between the LMC and the Milky Way cause dynamical perturbations in the MW halo, leading to biased distributions of stellar density and kinematics. We…
