Ionized gas metallicity of the strong [OIII]λ emission-line compact galaxies in the LAMOST survey
Siqi Liu, A-Li Luo, Wei Zhang +2
This article reports a sample of 1830 strong [O III] λ5007 emission-line compact galaxies discovered with the LAMOST spectroscopic survey and the photometric catalog of SDSS. We ne…
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…
Search for the metal-weak thick disk from the LAMOST DR5
T. -S. Yan, J. -R. Shi, H. Tian +2
Based on the data release of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope survey (LAMOST DR5) and the \emph{Gaia} Early Data Release 3 (\emph{Gaia} EDR3), we const…
Wolf-Rayet galaxies in SDSS-IV MaNGA. II. Metallicity dependence of the high-mass slope of the stellar initial mass function
Fu-Heng Liang, Cheng Li, Niu Li +4
As hosts of living high-mass stars, Wolf-Rayet (WR) regions or WR galaxies are ideal objects for constraining the high-mass end of the stellar initial mass function (IMF). We const…
A study of the HI gas fractions of galaxies at z ~ 1
Wei Zhang, Guinevere Kauffmann, Jing Wang +3
Due to the fact that HI mass measurements are not available for large galaxy samples at high redshifts, we apply a photometric estimator of the HI-to-stellar mass ratio (M_HI/M_*)…
Central velocity dispersion catalog of LAMOST-DR7 galaxies
Nicola R. Napolitano, Giuseppe D'Ago, Crescenzo Tortora +6
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) is a major facility to carry out spectroscopic surveys for cosmology and galaxy evolution studies. The sevent…
