WEAVE-QSO: A Massive Intergalactic Medium Survey for the William Herschel Telescope

M. M. Pieri, S. Bonoli, J. Chaves-Montero +12

In these proceedings we describe the WEAVE-QSO survey, which will observe around 400,000 high redshift quasars starting in 2018. This survey is part of a broader WEAVE survey to be…

HI 21-cm absorption survey of quasar-galaxy pairs: Distribution of cold gas around z<0.4 galaxies

R. Dutta, R. Srianand, N. Gupta +4

We present the results from our survey of HI 21-cm absorption, using GMRT, VLA and WSRT, in a sample of 55 z<0.4 galaxies towards radio sources with impact parameters (b) in the ra…

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…

Discovery of a Perseus-like cloud in the early Universe: HI-to-H2 transition, carbon monoxide and small dust grains at zabs=2.53 towards the quasar J0000+0048

P. Noterdaeme, J. -K. Krogager, S. Balashev +10

We present the discovery of a molecular cloud at zabs=2.5255 along the line of sight to the quasar J0000+0048. We perform a detailed analysis of the absorption lines from ionic, ne…

The ESO UVES Advanced Data Products Quasar Sample - VI. Sub-Damped Lyman- Metallicity Measurements and the Circum-Galactic Medium

S. Quiret, C. Péroux, T. Zafar +8

The Circum-Galactic Medium (CGM) can be probed through the analysis of absorbing systems in the line-of-sight to bright background quasars. We present measurements of the metallici…

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…
