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…
Preliminary Exploration of Areal Density of Angular Momentum for Spiral Galaxies
Lan Zhang, Feilu Wang, Xiangxiang Xue +4
The specific angular momenta () of stars, baryons as a whole and dark matter haloes contain clues of vital importance about how galaxies form and evolve. Using a sample of 70…
Beyond spectroscopy. II. Stellar parameters for over twenty million stars in the northern sky from SAGES DR1 and Gaia DR3
Yang Huang, Timothy C. Beers, Hai-Bo Yuan +18
We present precise photometric estimates of stellar parameters, including effective temperature, metallicity, luminosity classification, distance, and stellar age, for nearly 26 mi…
Detection of multiple phase space overdensities of GSE stars by orbit integration
WenboWu, GangZhao, JiangChang +5
In N-body simulations, nearly radial mergers can form shell-like overdensities in the sky position and phase space () due to the combination of dynamical friction and tidal…
A Catalog of Distance Determinations for the LAMOST DR8 K Giants in the Galactic Halo
Lan Zhang, Xiang-Xiang Xue, Chengqun Yang +4
We present a catalog of distances for 19544 K giants drawn from LAMOST DR8. Most of them are located in the halo of the Milky Way up to ~120~kpc. There are 15% K giants without SDS…
Value-added catalog of M-giant stars in LAMOST DR9
Jing Li, Lin Long, Jing Zhong +9
In this work, we update the catalog of M-giant stars from the low-resolution spectra of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Data Release 9. There…
