Modeling Warm Absorption in HST/COS Spectrum of Mrk 290 with XSTAR
S. N. Zhang, L. Ji, T. R. Kallman +4
We present a new method to model a HST/COS spectrum, aimed to analyze intrinsic UV absorption from the outflow of Mrk 290, a Seyfert I galaxy. We use newly updated XSTAR to generat…
SMT CO (2-1) Observations of Nearby Star-Forming Galaxies
Xue-Jian Jiang, Zhong Wang, Qiusheng Gu +2
We present CO =2-1 observations towards 32 nearby gas-rich star-forming galaxies selected from the ALFALFA and WISE catalogs, using the Sub-millimeter Telescope. Our sample is s…
Inefficient Star Formation In Extremely Metal Poor Galaxies
Yong Shi, Lee Armus, George Helou +5
The first galaxies contain stars born out of gas with little or no metals. The lack of metals is expected to inhibit efficient gas cooling and star formation but this effect has ye…
Color-Magnitude Distribution of Face-on Nearby Galaxies in SDSS DR7
Shuo-Wen Jin, Qiusheng Gu, Song Huang +2
We have analyzed the distributions in the color-magnitude diagram (CMD) of a large sample of face-on galaxies to minimize the effect of dust extinctions on galaxy color. About 300…
The Broad Wing of [O III] λ5007 Emission Line in Active Galactic Nuclei
Zhixin Peng, Yanmei Chen, Qiusheng Gu +1
We use a type 2 AGN sample from SDSS DR7 in which the [O III] λ5007 emission line can be modeled by two Gaussian components, a broad wing plus a narrow core, to investigate the ori…
