The size-velocity dispersion relationship of Galactic HII regions
Lin Ma, Yunning Zhao, Wei Zhang +11
The size-velocity dispersion () relation, while well established for giant HII regions, remains uncertain for their smaller counterparts (physical radii R < 20 pc). Thanks to th…
The HI gas fraction scaling relation of the Green Pea galaxies
Siqi Liu, A-Li Luo, Wei Zhang +3
Green Pea galaxies are compact galaxies with high star formation rates. However, limited samples of Green Pea galaxies have HI 21 cm measurements. Whether the HI gas fraction f_{HI…
Photometric Redshift Estimation of BASS DR3 Quasars by Machine Learning
Changhua Li, Yanxia Zhang, Chenzhou Cui +9
Correlating BASS DR3 catalogue with ALLWISE database, the data from optical and infrared information are obtained. The quasars from SDSS are taken as training and test samples whil…
Binary fraction of O and B-type stars from LAMOST data
Feng Luo, Yong-Heng Zhao, Jiao Li +2
Binary stars plays important role in the evolution of stellar populations . The intrinsic binary fraction () of O and B-type (OB) stars in LAMOST DR5 was investigated in t…
The Relative Calibration of Radial Velocity for LAMOST Medium Resolution Stellar Spectra
Jianping Xiong, Bo Zhang, Chao Liu +3
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) started median-resolution spectroscopic (MRS, R7500) survey since October 2018. The main scientific goa…
LAMOST Medium-Resolution Spectral Survey of Galactic Nebulae (LAMOST-MRS-N): Subtraction of Geocoronal Halpha Emission
Wei Zhang, Hong Wu, Chaojian Wu +10
We introduce a method of subtracting geocoronal Halpha emissions from the spectra of LAMOST medium-resolution spectral survey of Galactic nebulae (LAMOST-MRS-N). The flux ratios of…
