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…
Gradients of Stellar Population Properties and Evolution Clues in a Nearby Galaxy M 101
Lin Lin, Hu Zou, Xu Kong +4
Multi-band photometric images from ultraviolet and optical to infrared are collected to derive spatially resolved properties of a nearby Scd type galaxy M 101. With evolutionary st…
The Correlation between X-ray and UV Properties of BAL QSOs
LuLu Fan, HuiYuan Wang, Tinggui Wang +4
We compile a large sample of broad absorption lines (BAL) quasars with X-ray observations from the \xmm archive data and Sloan Digital Sky Survey Data Release 5. The sample consist…
Wolf-Rayet Galaxies in the Sloan Digital Sky Survey: the metallicity dependence of the initial mass function
Wei Zhang, Xu Kong, Cheng Li +2
We use a large sample of 174 Wolf-Rayet (WR) galaxies drawn from the Sloan Digital Sky Survey to study whether and how the slope of the stellar initial mass function depends on met…
Oxygen abundance in the Sloan Digital Sky Survey
F. Shi, X. Kong, F. Z. Cheng
We present two samples of $\hii$ galaxies from the Sloan Digital Sky Survey (SDSS) spectroscopic observations data release 3. The electron temperatures() of 225 galaxies are c…
