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_*)…
A New Transition Wolf-Rayet WN/C Star in the Milky Way
Wei Zhang, Helge Todt, Hong Wu +7
We report the discovery of a new transition type Wolf-Rayet (WR) WN/C star in the Galaxy. According to its coordinates (R.A., Dec)J2000 = 18h51m39.7s, -05d34m51.1s, and the distanc…
On the radial velocity calibrations in the LAMOST Medium-Resolution Spectroscopic Survey of Nebulae
Juan-Juan Ren, Hong Wu, Chao-Jian Wu +12
Accurate radial velocity determinations of optical emission lines (i.e. [NII]6548,6584, H, and [SII]6717,6731) are very important for investigating the kinematics and dy…
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…
LAMOST Medium-Resolution Spectroscopic Survey (LAMOST-MRS): Scientific goals and survey plan
Chao Liu, Jianning Fu, Jianrong Shi +38
Since September 2018, LAMOST starts a new 5-year medium-resolution spectroscopic survey (MRS) using bright/gray nights. We present the scientific goals of LAMOST-MRS and propose a…
Wolf-Rayet galaxies in SDSS-IV MaNGA. I. Catalog construction and sample properties
Fu-Heng Liang, Cheng Li, Niu Li +5
Wolf-Rayet (WR) galaxies are a rare population of galaxies that host living high-mass stars during their WR phase (i.e. WR stars) and are thus expected to provide interesting const…
