Abstract / Description of output

The results from a deep K-band imaging study,which reveals the host galaxies around a sample of luminous radio-quiet quasars, are shown to be important for models of the quasar population. The K-band images, obtained at UKIRT, were of sufficient quality to allow accurate 2D modelling of the underlying host galaxy. The derived average K-band absolute K-corrected host galaxy magnitude for these luminous radio-quiet quasars is (M-K) = -25.15+/-0.04, comparable to luminosities derived from samples of quasars of lower total luminosity. Nuclear-to-host ratios therefore break the lower limit previously suggested from studies of lower nuclear luminosity quasars and Seyfert galaxies. We show how simple theoretical models of quasar activity predict such a Emit, and suggest how this picture must be changed in light of our results.
