A Comprehensive Study of Morphology and Kinematics in Extended Nebulae Around UV Luminous Quasars at
Zhuoqi Liu, Sean D. Johnson, Eric F. Bell +22
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…
MUSEQuBES: Physical conditions, origins, and multi-element abundances of the circumgalactic medium of an isolated, star-forming dwarf galaxy at z=0.57
Sean D. Johnson, Nishant Mishra, Sowgat Muzahid +13
In dwarf galaxy models, outflows expel metal-enriched interstellar medium (ISM) into the circumgalactic medium (CGM) to reproduce their observed low metallicities, but measurements…
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…
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…
