We investigate multicolour imaging data of a complete sample of 19 low redshift (z < 0.2) quasar host galaxies. The sample was imaged in four optical (BVRi) and three near-infrared bands (JHKs). Galaxy types, structural parameters and robust host gala xy luminosities are extracted for all bands by means of two-dimensional deblending of galaxy and nucleus. For the disc dominated fraction of host galaxies (Sa and later) the o ptical and optical-to-NIR colours agree well with the average colours…

Star formation in luminous quasar host galaxies at z=1-2
We present deep HST/WFPC2, rest-frame U images of 17 ~L* quasars at z=1 and z=2 (V and I bands respectively), designed to explore the host galaxies. We fit the images with simple axisymmetric galaxy
Type II Quasars from the Sloan Digital Sky Survey
Type II quasars are luminous active galactic nuclei (AGNs) whose centers are obscured by large amounts of gas and dust. In this paper we present three-band Hubble Space Telescope images of nine type

A low-luminosity type-1 QSO sample - I. Overluminous host spheroidals or undermassive black holes?
Recognizing the properties of the host galaxies of quasi-stellar objects (QSOs) is essential to understand the suspected coevolution of central supermassive black holes (BHs) and their host galaxies.
