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…
