Abstract:
The circumgalactic 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 metallicity of a new sample of 15
sub-damped Lyman α absorbers (sub-DLAs, defined as absorbers
with 19.0 zabs≤3.104 from the ESO Ultra-Violet Echelle
Spectrograph (UVES) Advanced Data Products Quasar Sample (EUADP). We
combine these results with other measurements from the literature to
produce a compilation of metallicity measurements for 92 sub-DLAs as
well as a sample of 362 DLAs. We apply a multi-element analysis to
quantify the amount of dust in these two classes of systems. We find
that either the element depletion patterns in these systems differ
from the Galactic depletion patterns or they have a different
nucleosynthetic history than our own Galaxy. We propose a new method
to derive the velocity width of absorption profiles, using the
modelled Voigt profile features. The correlation between the velocity
width ΔV90 of the absorption profile and the metallicity is
found to be tighter for DLAs than for sub-DLAs. We report hints of a
bimodal distribution in the [Fe/H] metallicity of low redshift
(z<1.25) sub-DLAs, which is unseen at higher redshifts. This feature
can be interpreted as a signature from the metal-poor, accreting gas
and the metal-rich, outflowing gas, both being traced by sub-DLAs at
low redshifts.
Description:
In order to put together a significant sample of sub-DLAs observed at
high spectral resolution, we make use of the ESO UVES Advanced Data
Products (EUADP) sample from Zafar et al. (2013A&A...556A.140Z 2013A&A...556A.140Z). This
sample consists of 250 high-resolution (R∼42000) quasars spectra
covering a total of 196 damped absorbers (with log N(HI)>19.0).
We present here the analysis of 14 new EUADP sub-DLAs covering a
redshift range 0.584≤zabs≤3.104. We also include six new DLAs
for completeness. The measurements of HI column densities and
redshifts of each system in the EUADP sample are reported in Zafar et
al. (2013A&A...556A.140Z 2013A&A...556A.140Z) and references therein.

VLT/UVES by our group (see text for details), else, absorbers are from the
EUADP sample (Zafar et al., 2013A&A...556A.140Z 2013A&A...556A.140Z).
Note (G2): For PKS 0454-220, the abundances with the asterisk have been derived
