Multi-phase Circum-Galactic Medium probed with MUSE and ALMA
Celine Peroux, Martin Zwaan, Anne Klitsch +9
Galaxy halos appear to be missing a large fraction of their baryons, most probably hiding in the circumgalactic medium (CGM), a diffuse component within the dark matter halo that e…
Characterizing circumgalactic gas around massive ellipticals at z~0.4 III. The galactic environment of a chemically-pristine Lyman limit absorber
Hsiao-Wen Chen, Sean D. Johnson, Lorrie A. Straka +7
This paper presents a study of the galactic environment of a chemically-pristine (<0.6% solar metallicity) Lyman Limit system (LLS) discovered along the sightline toward QSO SDSSJ1…
Galaxy and Quasar Fueling Caught in the Act from the Intragroup to the Interstellar Medium
Sean D. Johnson, Hsiao-Wen Chen, Lorrie A. Straka +11
We report the discovery of six spatially extended (10-100 kpc) line-emitting nebulae in the z=0.57 galaxy group hosting PKS0405-123, one of the most luminous quasars at z<1. The di…
The extent of chemically enriched gas around star-forming dwarf galaxies
Sean D. Johnson, Hsiao-Wen Chen, John S. Mulchaey +2
Supernova driven winds are often invoked to remove chemically enriched gas from dwarf galaxies to match their low observed metallicities. In such shallow potential wells, outflows…
Observational signatures of a warped disk associated with cold-flow accretion
Hadi Rahmani, Céline Péroux, Ramona Augustin +9
We present MUSE observations of the field of the quasar Q0152020 whose spectrum shows a Lyman limit system (LLS) at redshift , with a metallicity Z $\gtrsim…
