cds-question@unistra.frquasarsspectroscopyredshiftedWe present a study of CIV absorption in a sample of 63 damped Lyman-{alpha} (DLA) systems and 11 sub-DLAs in the redshift range 1.75<z_abs_<3.61, using a dataset of high-resolution (6.6km/s FWHM), high signal-to-noise VLT/UVES spectra. The complex absorption line profiles show both narrow and broad CIV components, indicating the presence of both warm, photoionized and hot, collisionally ionized gas. We report new correlations between the metallicity (measured in the neutral-phase) and each of the CIV column density, the CIV total line width, and the maximum CIV velocity.2007A&A...473..791Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/473/791CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/other/PASA/19.455 : Damped Lyman alpha absorption of QSOs (Curran+, 2002)J/MNRAS/354/L31 : SDSS DR2 QSO and DLA properties (Murphy+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/473/791https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/473/791http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/473/791https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/473/791https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/473/791http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/473/791GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/473/791/position (QSO positions, from Simbad)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/473/791/position?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/473/791/position?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/473/791/position?GETtext/xml+votable180.050000true3.2756250.07552780.0055555555555555566/4168 4279 8395 12563 16640 16644 16752 16798 17314 17317 17404 17917 18039 18084 18086 18769 19680 19682 20516 21012 22917 25009 25294 25307 25628 25950 26175 26453 26479 26614 26882 27650 27652 27728 27747 28039 33971 34210 34379 34437 34503 34763 35576 35737 35751 35781 35842 35901 38853 38878 39100 45525 46529 46542 46651 46851 46856 48149 48154 48474https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/473/791?format=asciiOpticaldefaultJ/A+A/473/791/positionQSO positions, from SimbadSNameSimbad namemeta.idcharrecnoRecord number assigned by the VizieR team.
