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…
H I Properties of Field Galaxies at -0.6: Insights into Declining Cosmic Star Formation
David DePalma, Neeraj Gupta, Hsiao-Wen Chen +18
We report statistically significant detection of H I 21-cm emission from intermediate-redshift (-0.6) galaxies. By leveraging multi-sightline galaxy survey data from t…
Microphysics of Circumgalactic Turbulence Probed by Fast Radio Bursts and Quasars
S. K. Ocker, M. Chen, S. P. Oh +1
The circumgalactic medium (CGM) is poorly constrained at the sub-parsec scales relevant to turbulent energy dissipation and regulation of multi-phase structure. Fast radio bursts (…
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…
Resolving turbulence drivers in two luminous obscured quasars with JWST/NIRSpec IFU
Mandy C. Chen, Hsiao-Wen Chen, Michael Rauch +10
In this Letter, we investigate the turbulence and energy injection in the extended nebulae surrounding two luminous obscured quasars, WISEA J100211.29013706.7 () and S…
