On the Kinematics of Cold, Metal-enriched Galactic Fountain Flows in Nearby Star-forming Galaxies
Kate H. R. Rubin, Christian Juarez, Kathy L. Cooksey +7
We use medium-resolution Keck/Echellette Spectrograph and Imager spectroscopy of bright quasars to study cool gas traced by CaII 3934,3969 and NaI 5891,5897 absorption in the inter…
The Bimodal Absorption System Imaging Campaign (BASIC) I. A Dual Population of Low-metallicity Absorbers at z
Michelle A. Berg, Nicolas Lehner, J. Christopher Howk +17
The bimodal absorption system imaging campaign (BASIC) aims to characterize the galaxy environments of a sample of 36 HI-selected partial Lyman limit systems (pLLSs) and Lyman limi…
Damped Ly-alpha Absorbers in Star-forming Galaxies at z < 0.15 Detected with the Hubble Space Telescope and Implications for Galaxy Evolution
Varsha P. Kulkarni, David V. Bowen, Lorrie A. Straka +4
We report {\it HST} COS spectroscopy of 10 quasars with foreground star-forming galaxies at 0.02 0.14 within impact parameters of 1-7 kpc. We detect damped/sub-dampe…
The Geometry of Cold, Metal-Enriched Gas Around Galaxies at
Britt F. Lundgren, Samantha Creech, Gabriel Brammer +10
We present the first results from a Hubble Space Telescope WFC3/IR program, which obtained direct imaging and grism observations of galaxies near quasar sightlines with a high freq…
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…
Properties and redshift evolution of star-forming galaxies with high [OIII]/[OII] ratios with MUSE at 0.28<z<0.85
M. Paalvast, A. Verhamme, L. A. Straka +21
We present a study of the [OIII]5007/[OII]3727 (O32) ratios of star-forming galaxies drawn from MUSE data spanning a redshift range 0.28<z<0.85. Recently discovered Lyman continuum…
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…
Dark Galaxy Candidates at Redshift ~3.5 Detected with MUSE
Raffaella Anna Marino, Sebastiano Cantalupo, Simon J. Lilly +18
Recent theoretical models suggest that the early phase of galaxy formation could involve an epoch when galaxies are gas-rich but inefficient at forming stars: a "dark galaxy" phase…
Nature of the Absorbing Gas associated with a Galaxy Group at z~0.4
Celine Peroux, Hadi Rahmani, Samuel Quiret +6
We present new MUSE observations of quasar field Q2131-1207 with a log N(HI)=19.50+/-0.15 sub-DLA at z_abs=0.42980. We detect four galaxies at a redshift consistent with that of th…
Ubiquitous giant Ly nebulae around the brightest quasars at revealed with MUSE
Elena Borisova, Sebastiano Cantalupo, Simon J. Lilly +17
Direct Ly imaging of intergalactic gas at has recently revealed giant cosmological structures around quasars, e.g. the Slug Nebula (Cantalupo et al. 2014). Despite the…
A SINFONI Integral Field Spectroscopy Survey for Galaxy Counterparts to Damped Lyman-alpha Systems - VI. Metallicity and Geometry as Gas Flow Probes
Celine Peroux, Samuel Quiret, Hadi Rahmani +7
The use of background quasars provides a powerful tool to probe the cool gas in the circum-galactic medium of foreground galaxies. Here, we present new observations with SINFONI an…
