    Infrared properties of blazars: putting the GASP-WEBT sources into context
    The infrared properties of blazars can be studied from the statistical point of view with the help of sky surveys, like that provided by the Wide-field Infrared...

    Integral field spectroscopy of nearby quasi-stellar objects - II. Molecular gas content and conditions for star formation
    We present single-dish 12CO(1-0) and 12CO(2-1) observations for 14 low-redshift quasi-stellar objects (QSOs). In combination with optical integral field...

    Integral field spectroscopy of the gravitational lens HE1104-1805
    We present integral field spectroscopy of the double imaged quasar HE1104-1805 taken with the optical fiber system INTEGRAL-WYFFOS at the WHT telescope. From...

    Interactions between large-scale radio structures and gas in a sample of optically selected type 2 quasars
    Context. The role of radio mode feedback in non radio-loud quasars needs to be explored in depth to determine its true importance. Its effects can be identified...

    Intermediate-resolution spectropolarimetry of 3C 273
    Spectropolarimetric observations of the quasar 3C 273 over the range 3200-8000 A show wavelength-dependent polarization in the continuum, while the lines had no...
  • Publication
    Intermediate-resolution spectropolarimetry of a small sample of quasars
    We present spectropolarimetric observations of a sample of three quasars selected because of their very different broad-band polarization properties. All of the...

    Ionised AGN outflows in the Goldfish galaxy: The illuminating and interacting red quasar eFEDSJ091157.4+014327 at z ∼ 0.6
    Context. Evolutionary models suggest that the initial growth phases of active galactic nuclei (AGN) and their central supermassive black holes (SMBHs) are dust...

    Ionized outflows in luminous type 2 AGNs at z < 0.6: no evidence for significant impact on the host galaxies
    We investigate the presence of extended ionized outflows in 18 luminous type 2 AGNs (11 quasars and 7 high-luminosity Seyfert 2s) at 0.3 z 0.6 based on VLT...
