The Narrow Emission Lines of Seyfert 1 Galaxies: Comparisons with a Large SDSS Sample
Matthew Malkan, Lisbeth Jensen, Lei Hao
We analyzed a large sample of SDSS spectra of Seyfert galaxies, subdividing Seyfert 1s based on their narrow-to-broad Halpha components. Comparing their narrow-lines (NL) to Seyfer…
Multi-Component Ionized Gas Outflows in a Hot Dust-Obscured Galaxy W2026+0716 with Keck/OSIRIS
Chao Liu, Chao-Wei Tsai, Peter R. M. Eisenhardt +15
We present narrowband-filtered integral field unit (IFU) observations of the Hot Dust-Obscured Galaxy (Hot DOG) WISE J202615.27071624.0 (hereafter W20260716) at redshift $z=2…
Metal-strong Inflows at the Outer-galactic-scale of a Quasar
Qiguo Tian, Lei Hao, Yipeng Zhou +6
We present an analysis of the absorption-line system in the Very Large Telescope/Ultraviolet and Visual Echelle Spectrograph spectrum at a redshift of associat…
Radial Profiles of , , Gas Metallicity and Their Correlations Across the Galactic Mass-Size Plane
Lin Lin, Shiyin Shen, Hassen M. Yesuf +2
We analyzed the global and resolved properties of approximately 1,240 nearby star-forming galaxies from the MaNGA survey, comparing compact and extended galaxies -- those with smal…
The Clumpy Structure Of Five Star-bursting Dwarf Galaxies In The MaNGA Survey
Mengting Ju, Jun Yin, Lei Hao +6
The star-forming clumps in star-bursting dwarf galaxies provide valuable insights into the understanding of the evolution of dwarf galaxies. In this paper, we focus on five star-bu…
Linking the Metallicity Enrichment History to the Star Formation History: An SFH-regulated Chemical Evolution Model and Its Implications for the Gas Cycling Process
Jun Yin, Shiyin Shen, Lei Hao
The metallicity enrichment history (MEH) of a galaxy is determined by its star formation history (SFH) and the gas cycling process. In this paper, we construct a chemical evolution…
Host galaxy-active galactic nucleus alignments in the SDSS-DR7
Claudia del P. Lagos, Nelson D. Padilla, Michael A. Strauss +2
We determine the intrinsic shapes and orientations of 27,450 type I and II active galactic nucleus (AGN) galaxies in the spectroscopic sample of the SDSS DR7, by studying the distr…
Active Galactic Nuclei in the Sloan Digital Sky Survey: I. Sample Selection
Lei Hao, Michael A. Strauss, Christy A. Tremonti +18
We have compiled a large sample of low-redshift active galactic nuclei (AGN) identified via their emission line characteristics from the spectroscopic data of the Sloan Digital Sky…
Active Galactic Nuclei in the Sloan Digital Sky Survey: II. Emission-Line Luminosity Function
Lei Hao, Michael A. Strauss, Xiaohui Fan +18
The emission line luminosity function of active galactic nuclei (AGN) is measured from about 3000 AGN included in the main galaxy sample of the Sloan Digital Sky Survey within a re…
