The importance of galaxy interactions in triggering type II quasar activity
We present deep Gemini Multi-Object Spectrograph-South optical broad-band images for a complete sample of 20 Sloan Digital Sky Survey selected type II quasars taken from Zakamska et al., with redshifts in the range 0.3 z 0.41 and [O III]λ5007 emission-line luminosities L[O iii ]>108.5 L . The images were taken with the aim of investigating the
