    Properties of dusty tori in active galactic nuclei - I. The case of SWIRE/SDSS quasars
    We derive the properties of dusty tori in active galactic nuclei from the comparison of observed spectral energy distributions (SEDs) of SDSS quasars and a...

    QSO2 outflow characterization using data obtained with OSIRIS at the Gran Telescopio Canarias
    Context. Ionized outflows are ubiquitous in non-radio-loud obscured quasars (QSO2s) at different redshifts. However, the actual size of the outflows and their...
