We analyse a sample of 69 quasi-stellar objects (QSOs) which have been randomly selected in a complete sample of 104 QSOs (R ≤ 18,0.142 < z < 0.198,δ < 10°). 60 have been observed with the NTT/SUSI2 at La Silla, through two filters in the optical band (WB 655 and V 812), and the remaining nine are taken from archive data bases. The filter V 812 contains the redshifted H,β and forbidden [O III] emission lines, while WB 655 covers a spectral region devoid of emission lines, thus measuring the QSO… 
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
Low-redshift quasars in the Sloan Digital Sky Survey Stripe 82. The host galaxies
We present a photometrical and morphological study of the properties of low redshift (z < 0.5) quasars based on a large and homogeneous dataset of objects derived from the Sloan Digital Sky Survey
The Role of Major Mergers and Nuclear Star Formation in Nearby Obscured Quasars
We investigate the triggering mechanism and the structural properties of obscured luminous active galactic nuclei from a detailed study of the rest-frame $B$ and $I$ HST images of 29 nearby
Testing the Evolutionary Link between Type 1 and Type 2 Quasars with Measurements of the Interstellar Medium
In a popular scenario for the coevolution of massive black holes and galaxies, major mergers of gas-rich galaxies fuel vigorous star formation and obscured (type 2) quasar activity until energy
It is not yet clear what triggers the activity of active galactic nuclei (AGNs), but galaxy merging has been suspected to be one of the main mechanisms fuelling the activity. Using deep optical
Morphologies of z ∼ 0.7 AGN host galaxies in CANDELS: no trend of merger incidence with AGN luminosity
The processes that trigger active galactic nuclei (AGN) remain poorly understood. While lower luminosity AGN may be triggered by minor disturbances to the host galaxy, stronger disturbances are
Detection of Far-Infrared Emission from Galaxies and Quasars in the Galactic Extinction Map by Stacking Analysis
We have performed stacking image analyses of galaxies over the Galactic extinction map constructed by Schlegel, Finkbeiner & Davis (1998). We select ~10^7 galaxies in total from the Sloan Digital Sky
The drivers of AGN activity in galaxy clusters: AGN fraction as a function of mass and environment
We present an analysis of optical spectroscopically identified active galactic nuclei (AGN) down to a cluster magnitude of M ★ + 1 in a sample of six self-similar Sloan Digital Sky Survey galaxy
Evidence for a Young Stellar Population in Nearby Type 1 Active Galaxies
To understand the physical origin of the close connection between supermassive black holes and their host galaxies, it is vital to investigate star formation properties in active galaxies. Using a
Do we expect most AGN to live in discs
Recent observations have indicated that a large fraction of the low- to intermediate-luminosity AGN population lives in disc-dominated hosts, while the more luminous quasars live in bulge-dominated


The Fundamental Plane of QSOs and the Relationship between Host and Nucleus
We present results from an archival study of 70 medium-redshift QSOs observed with HST's WFPC2. The QSOs have magnitudes MV ≤ − 23 (total nuclear plus host light) and redshifts 0.06 ≤ z ≤ 0.46. The
Understanding the relations between QSOs and their host galaxies from combined HST imaging and VLT spectroscopy
host galaxies of six nearby QSOs are studied on the basis of high-resolution HST optical images and spatially resolved VLT slit spectra. The gas ionization and velocity are mapped as a function of
On-axis spectroscopy of the host galaxies of 20 optically luminous quasars at z ~ 0.3
We present the analysis of a sample of 20 bright low-redshift quasars (M B < - 23 and z < 0.35) observed spectroscopically with the Very Large Telescope (VLT). The Focal Reducer/low dispersion
Quasar host galaxy star formation activity from multicolour data
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).
Colors of AGN host galaxies at 0.5
We present the results from a study of the host galaxies of 15 optically selected AGNs with 0.5<z<1.1 from GEMS. GEMS is a Hubble Space Telescope imaging survey of a ~28"x28" contiguous field
Quasars, their host galaxies and their central black holes
We present the final results from our deep Hubble Space Telescope (HST) imaging study of the host galaxies of radio-quiet quasars (RQQs), radio-loud quasars (RLQs) and radio galaxies (RGs). We
