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…

Kinematics of H I and O VI Absorbers: Insights into the Turbulence Driver of the Multiphase Circumgalactic Medium
Zhijie Qu, Hsiao-Wen Chen, Eliana Schiller +2
We investigate large-scale gas kinematics in the multiphase circumgalactic medium (CGM) using the observed correlation between line width (Doppler parameter) and column density…

FEASTS Combined with Interferometry. III. The Low Column Density HI Around M51 and Possibility of Turbulent-mixing Gas Accretion
Xuchen Lin, Jing Wang, Lister Staveley-Smith +13
With a new joint-deconvolution pipeline, we combine the single-dish and interferometric atomic hydrogen (HI) data of M51 observed by the Five-hundred-meter Aperture Spherical radio…
