Two Portions of Sagittarius Stream in the LAMOST Complete Spectroscopic Survey of Pointing Area at Southern Galactic Cap
J. K. Zhao, X. H. Ye, H. Wu +6
We constructed a sample of 13,798 stars with , log , [Fe/H], radial velocity, proper motions and parallaxes from LAMOST DR5 and Gaia DR2 in the LAMOST Complete Spect…
A Mysterious Ring in Dark Space?
Wei Zhang, Fan Yang, Hong Wu +10
We report the discovery of a low-surface-brightness (27.42 mag arcsec^(-2) in g band) nebula, which has a ring-like shape in the Beijing-Arizona Sky Survey (BASS). Positive detecti…
Galaxy Optical Variability of Virgo Cluster: New Tracer for Environmental Influences on Galaxies
Fan Yang, Richard J. Long, Su-Su Shan +6
We investigate the relationship between the optical variability of galaxies and their distances from the centre of the Virgo Cluster using Palomar Transient Factory data. We define…
The galaxy luminosity function in the LAMOST Complete Spectroscopic Survey of Pointing Area at the Southern Galactic Cap
Pinsong Zhao, Hong Wu, C. K. Xu +13
We present optical luminosity functions (LFs) of galaxies in the , , and bands, calculated using data in sky area of LAMOST Complete…
Machine learning Applied to Star-Galaxy-QSO Classification and Stellar Effective Temperature Regression
Yu Bai, JiFeng Liu, Song Wang +1
In modern astrophysics, the machine learning has increasingly gained more popularity with its incredibly powerful ability to make predictions or calculated suggestions for large am…
An H Imaging Survey of the Low-surface-brightness Galaxies Selected from the Fall Sky Region of the 40 ALFALFA \ion{H}{1} Survey
Fengjie Lei, Hong Wu, Wei Du +11
We present the observed H flux and derived star formation rates (SFRs) for a fall sample of lowsurfacebrightness galaxies (LSBGs). The sample is selected from the fall sky…
The LAMOST Complete Spectroscopic Survey of Pointing Area (LaCoSSPAr) in the Southern Galactic Cap I. The Spectroscopic Redshift Catalog
Ming Yang, Hong Wu, Fan Yang +29
We present a spectroscopic redshift catalog from the LAMOST Complete Spectroscopic Survey of Pointing Area (LaCoSSPAr) in the Southern Galactic Cap (SGC), which is designed to obse…
Molecular Gas and Star-Formation In Low Surface Brightness Galaxies
Tian-Wen Cao, Hong Wu, Wei Du +12
We have obtained CO(J=2-1) spectra of nine face-on low surface brightness galaxies(LSBGs) using the JCMT 15-meter telescope and observed Ha images using the 2.16-meter telescope of…
Spectral Identification of the u-band Variable Sources in Two LAMOST fields
TianWen Cao, Ming Yang, Hong Wu +17
We selected 82 u-band variable objects based on the u-band photometry data from SCUSS and SDSS, in the field of LAMOST Complete Spectroscopic Survey of Pointing Area at Southern Ga…
The K giant stars from the LAMOST survey data I: identification, metallicity, and distance
Chao Liu, Li-Cai Deng, Jeffrey L. Carlin +10
We present a support vector machine classifier to identify the K giant stars from the LAMOST survey directly using their spectral line features. The completeness of the identificat…
LAMOST Experiment for Galactic Understanding and Exploration (LEGUE) The survey science plan
Licai Deng, Heidi Jo Newberg, Chao Liu +22
We describe the current plans for a spectroscopic survey of millions of stars in the Milky Way galaxy using the Guo Shou Jing Telescope (GSJT, formerly the Large Area Multi-Object…
The selection of LEGUE disk targets for LAMOST's pilot survey
Li Chen, Jinliang Hou, Jincheng Yu +18
We describe the target selection algorithm for the low latitude disk portion of the LAMOST Pilot Survey, which aims to test systems in preparation for the LAMOST spectroscopic surv…
