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
The stellar content of low redshift BL Lacertae host galaxies from multicolour imaging
Context. We present B -band imaging of 18 low redshift ($z \leq 0.3$) BL Lac objects for which their host galaxies were previously resolved in the R -band and the near-infrared H -band. For a subset

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.
Stellar Photometric Structures of the Host Galaxies of Nearby Type 1 Active Galactic Nuclei
We present detailed image analysis of rest-frame optical images of 235 low-redshift ($z \leq$ 0.35) type 1 active galactic nuclei (AGNs) observed with the Hubble Space Telescope. The high-resolution
Host galaxies of luminous quasars: population synthesis of optical off-axis spectra
There is increasing evidence of a connection between AGN activity and galaxy evolution. To obtain further insight into this potentially important e volutionary phase, we analyse the properties of
Galaxies hosting an active galactic nucleus: a view from the CALIFA survey
We study the presence of optically-selected Active Galactic Nuclei (AGNs) within a sample of 867 galaxies extracted from the extended {\it Calar-Alto Legacy Integral Field spectroscopy Area}
