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…

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…

Vertical structure of Galactic disk kinematics from LAMOST K giants

Ping-Jie Ding, Xiang-Xiang Xue, Chengqun Yang +3

We examine the vertical structure of Galactic disk kinematics over a Galactocentric radial distance range of and up to away from the Galactic pla…

Exploring the Galactic Anticenter substructure with LAMOST & Gaia DR2

Jing Li, Xiang-Xiang Xue, Chao Liu +12

We characterize the kinematic and chemical properties of 589 Galactic Anticenter Substructure Stars (GASS) with K-/M- giants in Integrals-of-Motion space. These stars likely includ…

Detection of the LMC-induced sloshing of the Galactic halo

Denis Erkal, Alis J. Deason, Vasily Belokurov +8

A wealth of recent studies have shown that the LMC is likely massive, with a halo mass . One consequence of having such a nearby and massive neighbour is that the…
