    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...

    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...

    Jets from Subparsec to Kiloparsec Scales: A Physical Connection
    The Chandra discovery of bright X-ray emission from kiloparsec-scale jets allows insight into the physical parameters of the jet flow at large scales. At the...

    JWST view of Polycyclic Aromatic Hydrocarbons and dust in local active galaxies
    Nowadays, it is widely accepted that most galaxies undergo an active phase in their evolution. The impact of the energy released by active galactic nuclei (AGN)...
