The Host Galaxies of Luminous Radio-Quiet Quasars

Abstract: A B S T R A C TWe present the results of a deep K-band imaging study which reveals the host galaxies around a sample of luminous radio-quiet quasars. The K-band images, obtained at UKIRT, are of sufficient quality to allow accurate modelling of the underlying host galaxy. Initially, the basic structure of the hosts is revealed using a modified clean deconvolution routine optimized for this analysis. Two of the 14 quasars are shown to have host galaxies with violently disturbed morphologies which cannot be mode… Show more

“…Although the universal validity of this boundary has recently been questioned by Percival et al (2000;also these proceedings), it is clearly present in our data. We therefore decided to incorporate it by multiplying the above expression by a factor H(L gal − xL nuc ) where H(t 1 − t 2 ) = 1 for t 1 > t 2 and 0 elsewhere is the Heavyside step function, and x is an adjustable parameter.…”

“…A summary of these observations is given in Table 1. For completeness, we have also included the photometry obtained by other groups as well (Giles et al 1999;Percival et al 1998;Homer et al 2001).…”

“…Still, a clear picture has not emerged, with some studies claiming a high fraction of disk morphologies amongst the radio-quiets (e.g. Percival et al 2000), whilst others suggest that nearly all quasars are in giant ellipticals (e.g. McLure et al 2000).…”
