cds-question@unistra.frquasarsactive-galactic-nucleiaccretionspectroscopyvisible-astronomyredshiftedWe use the spectra of 73 quasars (1.5=<z=<5) from the VLT UVES archive to catalogue and study narrow absorption lines (NALs) that are physically associated with (intrinsic to) the quasars. We identify 410 NAL systems containing CIV, NV, and/or SiIV doublets. Based on the assumption that only systems intrinsic to the quasar can exhibit partial coverage of the background source(s), we identify 34 reliably intrinsic NAL systems and 11 systems that are potentially intrinsic, as well as 4 mini-broad absorption lines (BALs) and 1 BAL. The minimum fraction of quasars with at least one intrinsic system is shown to be 38 per cent. We identify intrinsic NALs with a wide range of properties, including apparent ejection velocity, coverage fraction, and ionization level. There is a continuous distribution of properties, rather than discrete families, ranging from partially covered CIV systems with black Ly{alpha} and with a separate low-ionization gas phase to partially covered NV systems with partially covered Ly{alpha} and without detected low-ionization gas. Even more highly ionized associated and intrinsic absorption systems (OVI, NeVIII, and MgX doublets) have been presented in separate studies; these may represent an extension of the above sequence. We also use the properties of the NALs in conjunction with recent models of accretion disc winds that predict the origins of the absorbing gas in order to determine the model that best characterizes our sample. Additionally, we construct a model describing the spatial distributions, geometries, and varied ionization structures of intrinsic NALs.2019MNRAS.488.4690Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/488/4690CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/660/1093 : Weak MgII absorbers at 0.4<z<2.4 (Narayanan+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/488/4690https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/488/4690http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/488/4690https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/488/4690https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/488/4690http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/488/4690GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/488/4690/table1 (quasars and their properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/488/4690/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/488/4690/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/488/4690/table1?GETtext/xml+votable180.050000true0.9371436-23.39863140.0055555555555555566/4448 4850 16625 16640 16644 16656 16664 16752 18084 18086 18092 18210 18307 18366 19026 19490 20516 20731 25120 25142 25285 25344 25540 25697 25863 25950 26166 26479 26614 26881-26882 27161 27269 27650 27704 27747 27855 28548 31313 31686 33971 34019 34485 34570 34763 35213 35258 35496 35585 35595 35627 35751 35806 35836 35957 36130 36217 36417 43903 44269 46208 46418 46529 46704 46737 46856 47007 47091 47941 48149 48154 48474 48757https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/488/4690?format=asciiOpticaldefaultJ/MNRAS/488/4690/table1quasars and their propertiesSimbadNameSimbad column added by the CDSmeta.idcharnullablelogL4400Optical luminosity at 4400{AA} in the quasar rest framelog(1e-07W.Hz**-1)phys.luminosityfloatlogLradObserved radio luminosity (2)log(1e-07W.Hz**-1)phys.luminosity;em.radiofloatnuRadio frequency corresponding to the observed radio luminosityGHzem.freqfloatl_logL5GHzLimit flag on logL5GHzmeta.code.errorcharlogL5GHzRadio luminosity at 5GHz in the quasar rest frame, obtained from the observed luminosity using a spectra index of {alpha}_r_=0.7log(1e-07W.Hz**-1)phys.luminosity;em.radiofloatl_logRLimit flag on logRmeta.code.errorcharlogRRadio-loudness parameter (3)phot.flux;arith.ratiofloatL/Q[LQ?] Radio-loud (L) or radio-quiet (Q) quasar (4)meta.code.classchar_RARight Ascension (J2000) from SIMBAD (not part of the original data)degpos.eq.ra;meta.main_DEDeclination (J2000) from SIMBAD (not part of the original data)degpos.eq.dec;meta.mainrecnoRecord number assigned by the VizieR team.
