The ESO UVES Advanced Data Products Quasar Sample-V. Identifying the Galaxy Counterpart to the sub-Damped Ly-alpha System towards Q2239-2949
Tayyaba Zafar, Palle Møller, Céline Péroux +4
Gas flows in and out of galaxies are one of the key unknowns in todays' galaxy evolution studies. Because gas flows carry mass, energy and metals, they are believed to be closely c…
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…
A study of the circum-galactic medium at z ~ 0.6 using DLA-galaxies
Hadi Rahmani, Celine Peroux, David A. Turnshek +5
We present the study of a sample of nine QSO fields, with damped-Ly-alpha (DLA) or sub-DLA systems at z~0.6, observed with the X-Shooter spectrograph at the Very Large Telescope. B…
Parsec-scale HI absorption structure in a low-redshift galaxy seen against a Compact Symmetric Object
A. D. Biggs, M. A. Zwaan, E. Hatziminaoglou +2
We present global VLBI observations of the 21-cm transition of atomic hydrogen seen in absorption against the radio source J0855+5751. The foreground absorber (SDSS~J085519.05+5751…
The Detailed Science Case for the Maunakea Spectroscopic Explorer: the Composition and Dynamics of the Faint Universe
Alan McConnachie, Carine Babusiaux, Michael Balogh +173
MSE is an 11.25m aperture observatory with a 1.5 square degree field of view that will be fully dedicated to multi-object spectroscopy. More than 3200 fibres will feed spectrograph…
Element Abundances in a Gas-rich Galaxy at z = 5: Clues to the Early Chemical Enrichment of Galaxies
Sean Morrison, Varsha P. Kulkarni, Debopam Som +3
Element abundances in high-redshift quasar absorbers offer excellent probes of the chemical enrichment of distant galaxies, and can constrain models for population III and early po…
