cds-question@unistra.frquasarsgalaxiesvisible-astronomysloan-photometryredshiftedWe present photometric and spectroscopic measurements of 53 QSO-galaxy pairs from the Sloan Digital Sky Survey (SDSS), where nebular emission lines from a 0<z<0.84 foreground galaxy are detected in the fibre spectra of a background QSO, bringing the overall sample to 103 QSO-galaxy pairs detected in the SDSS. We here study the nature of these systems. Detected foreground galaxies appear at impact parameters between 0.37 and 12.68 kpc. The presence of oxygen and Balmer emission lines allows us to determine the emission line metallicities for our sample, which are on average supersolar in value. Star formation rates for our sample are in the range 0.01-12M_{sun}_/yr. We utilize photometric redshift fitting techniques to estimate the M* values of our galaxies (logM*=7.34-11.54), and extrapolate this relationship to those galaxies with no imaging detections. Where available, we measure the absorption features present in the QSO spectrum due to the foreground galaxy and the relationships between their rest equivalent widths. We report an anticorrelation between impact parameter and E(B-V)(g-i), as well as a correlation between galaxy colour (u- r) and E(B-V)(g-i). We find that our sample is one of late-type, star-forming galaxies comparable to field galaxies in a similar redshift range, providing important clues to better understand absorption systems. These galaxies represent a sample of typical galaxies in the local Universe for which abundances, extinction, morphology, and absorption properties may be measured using background QSOs with great potential for follow-up observations.2015MNRAS.447.3856Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/447/3856CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/447/3856https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/447/3856http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/447/3856https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/447/3856https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/447/3856http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/447/3856GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/447/3856/table1 (Catalogue of GOTOQs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/447/3856/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/447/3856/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/447/3856/table1?GETtext/xml+votable180.050000true3.426875-0.40350.0055555555555555566/908 4154 4314 4358 4423 4577 4649 4802 4955 4986 5121 5135 5199 5627 5646 5751 6056 6090 6106 6270 6455 7254 8253 8507 8543 9202 9281 9335 9475 9626 9847 9949-9950 9973 9978 10249 10290 10380 10649 10682 10704 10720 10813 11068 11106 11124 11242 11326 11395 11415 11462 11585 11832 11914 11937 17749 17755 17981 18022 18086 18775 18882 19111 19668 22008 23193 23206 25965 25972-25973 26002 26094 26589 27077 27117 27199 27213 27224 27346 27415 27488 27494 27521 27653 27741 27862 27872 27998 28002 28038 28223 28239 28263 28287 28494 28665 31414 31419 31535 31599 32439 32444 367902.040811542443644e-19 6.090060298487514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/447/3856?format=asciiOpticaldefaultJ/MNRAS/447/3856/table1Catalogue of GOTOQsSimbadNameSimbad column added by the CDSmeta.idcharnullableNameName (QHHMM+DDMM)meta.id;meta.maincharprimaryF[SII]a?
