Cloud-by-cloud Multiphase Investigation of the Circumgalactic Medium of Low-redshift Galaxies
Sameer, Jane C. Charlton, Bart P. Wakker +10
The pervasive presence of warm gas in galaxy halos suggests that the circumgalactic medium (CGM) is multiphase in its ionization structure and complex in its kinematics. Some recen…
Discovery of optically emitting circumgalactic nebulae around the majority of UV-luminous quasars at intermediate redshift
Sean D. Johnson, Zhuoqi Will Liu, Jennifer I. Li +15
We report the discovery of large ionized, [O II] emitting circumgalactic nebulae around the majority of thirty UV luminous quasars at observed with deep, wide-field int…
The first comprehensive study of a giant nebula around a radio-quiet quasar in the Universe
Zhuoqi Will Liu, Sean D. Johnson, Jennifer I-Hsiu Li +10
We present the first comprehensive study of a giant, kpc-scale nebula around a radio-quiet quasar at . The analysis is based on deep integral field spectros…
Directly tracing cool filamentary accretion over >100 kpc into the interstellar medium of a quasar host at z=1
Sean D. Johnson, Joop Schaye, Gregory L. Walth +11
We report the discovery of giant (50-100 kpc) [O II] emitting nebulae with the Multi-Unit Spectroscopic Explorer (MUSE) in the field of TXS 0206-048, a luminous quasar at z=1.13. D…
Cloud-by-cloud, multiphase, Bayesian modeling: Application to four weak, low ionization absorbers
Sameer, J. C. Charlton, J. M. Norris +8
We present a new method aimed at improving the efficiency of component by component ionization modeling of intervening quasar absorption line systems. We carry out cloud-by-cloud,…
The Highly Ionized Circumgalactic Medium is Kinematically Uniform Around Galaxies
Nikole M. Nielsen, Glenn G. Kacprzak, Sowgat Muzahid +3
The circumgalactic medium (CGM) traced by OVI doublet absorption has been found to concentrate along the projected major and minor axes of the host galaxies. This su…
