cds-question@unistra.frquasarsredshiftedline-intensitiesWe use the first data release of the 2-degree Field quasar survey (Cat. <VII/223>) to investigate the effect of gravitational magnification by foreground absorbing systems on background quasars. We select two populations of quasars from this sample: one with strong MgII/FeII absorbers and one without. The selection is done in such a way that the two populations have the same redshift distribution and the absorber detection procedure discards possible biases with quasar magnitude.2003A&A...410...33Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/410/33CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/223 : The 2dF QSO Redshift Survey.
