A North-South Metallicity Asymmetry in the Outer Galactic disk -- Evidence for the Pericentric Passage of the Sagittarius Dwarf Galaxy
Chun Wang, Yang Huang, Timothy C. Beers +4
We present maps of the mean metallicity distributions on the Galactocentric -- plane at different azimuthal angles using red clump stars selected from the LAMOST and APOGEE s…
The LAMOST Spectroscopic Survey of Supergiants in M31 and M33
Hao Wu, Yang Huang, Huawei Zhang +3
We present systematic identifications of supergiants of M31/M33 based on massive LAMOST spectroscopic survey. Radial velocities of nearly 5000 photometrically selected M31/M33 supe…
Mapping the Galactic disk with the LAMOST and Gaia Red clump sample: VIII: Mapping the kinematics of the Galactic disk using mono-age and mono-abundance stellar populations
Weixiang Sun, Yang Huang, Han Shen +5
We present a comprehensive study of the kinematic properties of the different Galactic disk populations, as defined by the chemical abundance ratios and stellar ages, across a larg…
Three-Dimensional Distribution of the Interstellar Dust in the Milky Way
H. -L. Guo, B. -Q. Chen, H. -B. Yuan +6
We present a three-dimensional (3D) extinction map of the southern sky. The map covers the SkyMapper Southern Survey (SMSS) area of 14,000 and has spatial re…
Mapping the Galactic disk with the LAMOST and Red clump sample: V: On the origin of the "young" [/Fe]-enhanced stars
Weixiang Sun, Yang Huang, Haifeng Wang +8
Using a sample of nearly 140,000 primary red clump stars selected from the LAMOST and surveys, we have identified a large sample of "young" [/Fe]-enhanced stars with stel…
Mapping the Galactic disk with the LAMOST and Gaia red clump sample: IV: the kinematic signature of the Galactic warp
X. -Y. Li, Y. Huang, B. -Q. Chen +5
Using a sample of nearly 140,000 red clump stars selected from the LAMOST and Gaia Galactic surveys, we have mapped mean vertical velocity in the - plane f…
On the kinematic signature of the Galactic warp as revealed by the LAMOST-TGAS data
Yang Huang, R. Schönrich, Xiaowei Liu +6
Using a sample of about 123,000 stars with accurate 3D velocity measurements from the LAMOST-TGAS data, we confirm the kinematic signature of the Galactic warp found by Schönrich &…
Discovery of two new hypervelocity stars from the LAMOST spectroscopic surveys
Yang Huang, Xiaowei Liu, Huawei Zhang +7
We report the discovery of two new unbound hypervelocity stars (HVSs) from the LAMOST spectroscopic surveys. They are respectively a B2V type star of ~ 7 M with a Gal…
A three dimensional extinction map of the Galactic Anticentre from multi-band photometry
B. -Q Chen, X. -W. Liu, H. -B. Yuan +8
We present a three dimensional extinction map in band. The map has a spatial angular resolution, depending on latitude, between 3 -- 9\,arcmin and covers the entire XSTPS-GAC s…
HST and LAMOST discover a dual active galactic nucleus in J0038+4128
Y. Huang, X. -W. Liu, H. -B. Yuan +6
We report the discovery of a kiloparsec-scale dual active galactic nucleus (AGN) in J0038+4128. From the Hubble Space Telescope (HST) Wide Field Planetary Camera (WFPC2) images, we…
Mapping the three-dimensional multi-band extinction and diffuse interstellar bands in the Milky Way with LAMOST
Haibo Yuan, Xiaowei Liu, Maosheng Xiang +4
With modern large scale spectroscopic surveys, such as the SDSS and LSS-GAC, Galactic astronomy has entered the era of millions of stellar spectra. Taking advantage of the huge spe…
LSS-GAC - A LAMOST Spectroscopic Survey of the Galactic Anti-center
X. -W. Liu, H. -B. Yuan, Z. -Y. Huo +10
As a major component of the LAMOST Galactic surveys, the LAMOST Spectroscopic Survey of the Galactic Anti-center (LSS-GAC) will survey a significant volume of the Galactic thin/thi…
