The Simulated Oxygen Shortage (SOS): Mapping the Missing OVI in Simulated Dwarf Galaxies to Subgrid Physics
Daniel R. Piacitelli, Alyson M. Brooks, N. Nicole Sanchez +9
Observations reveal extended \OVI\, reservoirs in the circumgalactic medium (CGM) of dwarf galaxies, yet current simulations systematically underpredict \OVI\, column densities. Ut…
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…
A new "temperature inversion" estimator to detect CMB patchy screening by large-scale structure
Theo Schutt, Abhishek S. Maniyar, Emmanuel Schaan +2
Thomson scattering of cosmic microwave background (CMB) photons imprints various properties of the baryons around galaxies on the CMB. One such imprint, called patchy screening, is…
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…
