We determined C, N and alpha-element relative abundances in the gas surrounding six QSOs at an average redshift of~ 2.4, by studying six narrow associated absorption systems in UVES high-resolution spectra. We found five systems with a metallicity (measured by C/H) consistent or above the solar value. The ionization structure observed in the associated systems is clearly different from that of the intervening ones, indicating that the associated systems are influenced by the strong UV flux from…

Chemical abundances in QSO host galaxies and environments
We determined C, N and -element relative abundances in the gas surrounding six QSOs at an average redshift of ' 2:4, by studying six narrow associated absorption systems in UVES high-resolution
The gaseous environments of quasars: associate absorption lines with density and distance constraints
Associated absorption lines (AALs) in quasar spectra are valuable probes of the gas kinematics and physical conditions in quasar environments. The host galaxies are by definition in an active
Hunting for metals using XQ-100 Legacy Survey composite spectra
We investigate the NV absorption signal along the line of sight of background quasars, in order to test the robustness of the use of this ion as criterion to select intrinsic (i.e. physically related
Nature and Origins of Rich Complexes of C iv Associated Absorption Lines
Rich complexes of associated absorption lines (AALs) in quasar spectra provide unique information about gaseous infall, outflows, and feedback processes in quasar environments. We study five quasars
A glance at the host galaxy of high-redshift quasars using strong damped Lyman-α systems as coronagraphs
We searched quasar spectra from the SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS) for the rare occurrences where a strong damped Lyman-α absorber (DLA) blocks the Broad Line Region emission
A deep search for metals near redshift 7 : the line of sight towards ULAS J1120+0641
We present a search for metal absorption line systems at the highest redshifts to date using a deep (30 h) Very Large Telescope/X-Shooter spectrum of the z = 7.084 quasi-stellar object (QSO) ULAS
An excess of damped Lyman α galaxies near quasi‐stellar objects
We present a sample of 33 damped Lyman a systems (DLAs) discovered in the Sloan Digital Sky Survey (SDSS) whose absorption redshifts (z abs ) are within 6000 km s -1 of the quasi-stellar object's
The effect of stellar feedback and quasar winds on the active galactic nucleus population
In order to constrain the physical processes that regulate and downsize the active galactic nucleus (AGN) population, the predictions of the model for the rise of galaxies and active nuclei (MORGANA)
Metallicity and far-infrared luminosity of high-redshift quasars
We present the results of an exploratory study of broad-line region (BLR) metallicity in 34 2.2 ≤ z ≤ 4.6 quasars with far-infrared (FIR) luminosities (L FIR ) from 10 13.4 to ≤10 12.1 L⊙. Quasar
QUASARS PROBING QUASARS. III. NEW CLUES TO FEEDBACK, QUENCHING, AND THE PHYSICS OF MASSIVE GALAXY FORMATION
Galaxies hosting z ~ 2 quasars are the high-z progenitors of today's massive red and dead galaxies. With close pairs of quasars at different redshifts, a background quasar can be used to study a
