MgII/FeII absorbers in 2dF-quasar survey

DOI

We use the first data release of the 2-degree Field quasar survey (Cat. ) 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.
