Spectral classification and composites of galaxies in LAMOST DR4
Li-Li Wang, A-Li Luo, Shi-Yin Shen +10
We study the classification and composite spectra of galaxy in the fourth data release (DR4) of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST). We select 40…
The peculiar in-plane velocities in the outer disc of the Milky Way
Hai-Jun Tian, Chao Liu, Jun-Chen Wan +9
We present the peculiar in-plane velocities derived from the LAMOST red clump stars, which are purified and separated by a novel approach into two groups with different ages. The s…
Mapping the Milky Way with LAMOST II: the stellar halo
Yan Xu, Chao Liu, Xiang-Xiang Xue +9
The radial number density and flattening of the Milky Way's stellar halo is measured with metal-poor ([Fe/H]) K giants from LAMOST DR3, using a nonparametric m…
Candidate members of the Pal 5, GD-1, Cetus Polar, and Orphan tidal stellar halo streams from Sdss DR9, Lamost DR3 and APOGEE catalogues
Guang-Wei Li, Brian Yanny, Hao-Tong Zhang +8
We present candidate members of the Pal 5, GD-1, Cetus Polar, and Orphan tidal stellar streams found in LAMOST DR3, SDSS DR9 and APOGEE catalogs. In LAMOST DR3, we find 20, 4, 24 h…
Quasars in the Galactic Anti-Center Area from the LAMOST DR3
Zhi-Ying Huo, Xiao-Wei Liu, Jian-Rong Shi +11
We present a sample of quasars discovered in the area of Galactic Anti-Center (GAC) of and , based on the LAMOST Data Rel…
The local spiral arm in the LAMOST-Gaia common stars?
Chao Liu, You-Gang Wang, Juntai Shen +7
Using the LAMOST-Gaia common stars, we demonstrate that the in-plane velocity field for the nearby young stars are significantly different from that for the old ones. For the young…
A sample of metal-poor galaxies identified from the LAMOST spectral survey
Yulong Gao, Jianhui Lian, Xu Kong +8
We present a sample of 48 metal-poor galaxies at selected from 92,510 galaxies in the LAMOST survey. These galaxies are identified for their detection of the auroral em…
Mapping the Milky Way with LAMOST I: Method and overview
Chao Liu, Yan Xu, Jun-Chen Wan +8
We present a statistical method to derive the stellar density profiles of the Milky Way from spectroscopic survey data, taking into account selection effects. We assume that the se…
