Stellar Density Classification and Regression for CSST Multi-color Imaging Using Deep Learning
Jinzhi Lai, Man I Lam, Jianjun Chen +6
The Chinese Space Station Survey Telescope (CSST) aims to map the universe across an unprecedented dynamic range of stellar densities, spanning from extragalactic voids to the crow…
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…
Exploring the formation mechanisms of tidal structures in globular clusters of extragalactic origin
Shouzhi Wang, Jundan Nie, Biwei Jiang +3
Tidal structures around globular clusters provide valuable insights into cluster evolution and the hierarchical assembly of the Milky Way. Using wide-field imaging data from the DE…
A Vertically Orientated Dark Matter Halo Marks a Flip of the Galactic Disk
Ling Zhu, Runsheng Cai, Xi Kang +5
Unveiling the 3D shape of the Milky Way's dark-matter halo is critical to understanding its formation history. We created an innovative dynamical model with minimal assumptions on…
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…
Assessing the Association between the Globular Cluster NGC 4147 and the Sagittarius Dwarf Galaxy
YingHua Zhang, Jundan Nie, Hao Tian +1
The potential association of the globular cluster (GC) NGC 4147 with the Sagittarius (Sgr) dwarf spheroidal galaxy has been proposed due to their comparable locations and radial ve…
Deciphering the Kinematic Substructure of Local Dark Matter with LAMOST K Giants
Hai Zhu, Rui Guo, Juntai Shen +5
Numerical simulations indicate that correlations exist between the velocity distributions of stars and dark matter (DM). We study the local DM velocity distribution based on these…
