A Comprehensive Study of Morphology and Kinematics in Extended Nebulae Around UV Luminous Quasars at

Zhuoqi Liu, Sean D. Johnson, Eric F. Bell +20

Gas flows between galaxies and the circumgalactic medium (CGM) play a central role in galaxy evolution and can become observable as giant nebulae when illuminated by the quasars. W…

Deep Ultraviolet, Emission-Line Imaging of the Makani Galactic Wind

Triet Ha, David Rupke, Shane Caraker +14

The OVI 1032, 1038 A line is a key probe of cooling gas in the circumgalactic medium (CGM) of galaxies, but has been observed to date primarily in absorption along single sightline…

The Morphology and Kinematics of a Giant, Symmetric Nebula Around a Radio-Loud Quasar 3C57: Extended Rotating Gas or Biconical Outflows?

Zhuoqi, Liu, Sean D. Johnson +12

Gas flows between galaxies and the CGM play a crucial role in galaxy evolution. When ionized by a quasar, these gas flows can be directly traced as giant nebulae. We present a stud…

Probing the He II re-Ionization ERa via Absorbing C IV Historical Yield (HIERACHY) II: Project Design, Current Status, and Examples of Initial Data Products

Jiang-Tao Li, Xiaodi Yu, Huiyang Mao +22

The He II reionization epoch is expected to take place at . In this stage, the helium and metals in the inter-galactic medium (IGM) are further ionized with additional co…

Merian: A Wide-Field Imaging Survey of Dwarf Galaxies at z~0.06-0.10

Shany Danieli, Erin Kado-Fong, Song Huang +32

We present the Merian Survey, an optical imaging survey optimized for studying the physical properties of bright star-forming dwarf galaxies. Merian is carried out with two medium-…

The Cosmic Ultraviolet Baryon Survey (CUBS) IX: The enriched circumgalactic and intergalactic medium around star-forming field dwarf galaxies traced by O VI absorption

Nishant Mishra, Sean D. Johnson, Gwen C. Rudie +13

The shallow potential wells of star-forming dwarf galaxies make their surrounding circumgalactic and intergalactic medium (CGM/IGM) sensitive laboratories for studying the inflows…
