Physical Properties of H II Regions in M51 from Spectroscopic Observations
Peng Wei, Hu Zou, Xu Kong +13
M51 and NGC 5195 is an interacting system that can be explored in great details with ground-based telescopes. The H II regions in M51 were observed using the 2.16 m telescope of th…
Dust Attenuation Curve for Local Subgalactic Star-forming Regions
Berzaf B. Teklu, Zesen Lin, Xu Kong +5
We compile a sample of about 157,000 spaxels from the Mapping Nearby Galaxies at the Apache Point Observatory survey to derive the average dust attenuation curve for subgalactic st…
What determines the local metallicity of galaxies: global stellar mass, local stellar mass surface density or star formation rate?
Yulong Gao, Enci Wang, Xu Kong +8
The metallicity and its relationship with other galactic properties is a fundamental probe of the evolution of galaxies. In this work, we select about 750,000 star-forming spatial…
M101: Spectral Observations of HII Regions and Their Physical Properties
Ning Hu, Enci Wang, Zesen Lin +11
By using the Hectospec 6.5 m Multiple Mirror Telescope (MMT) and the 2.16 m telescope of National Astronomical Observatories, Chinese Academy of Sciences (NAOC), we obtained 188 hi…
Spectroscopic Observation and Analysis of HII regions in M33 with MMT: Temperatures and Oxygen Abundances
Zesen Lin, Ning Hu, Xu Kong +7
The spectra of 413 star-forming (or HII) regions in M33 (NGC 598) were observed by using the multifiber spectrograph of Hectospec at the 6.5-m Multiple Mirror Telescope (MMT). By u…
A sample of metal-poor galaxies identified from the LAMOST spectral survey
Yulong Gao, Jianhui Lian, Xu Kong +8
We present a sample of 48 metal-poor galaxies at selected from 92,510 galaxies in the LAMOST survey. These galaxies are identified for their detection of the auroral em…
The metallicity evolution of blue compact dwarf galaxies from the intermediate redshift to the local Universe
Jianhui Lian, Ning Hu, Guanwen Fang +2
We present oxygen abundance measurements for 74 blue compact dwarf (BCD) galaxies in the redshift range in [0.2, 0.5] using the strong-line method. The spectra of these objects are…
Spectral Synthesis via Mean Field approach Independent Component Analysis
Ning Hu, Shan-Shan Su, Xu Kong
In this paper, we apply a new statistical analysis technique, Mean Field approach to Bayesian Independent Component Analysis (MF-ICA), on galaxy spectral analysis. This algorithm c…
The First Data Release (DR1) of the LAMOST general survey
A. -L. Luo, Y. -H. Zhao, G. Zhao +140
The Large sky Area Multi-Object Spectroscopic Telescope (LAMOST) General Survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and…
