    Improvement of the Hubble diagram for QSO's leading towards g(O)
    Using the predictions of the Lynden Bell/Hills model of the energy source of QSO's in which discrete packets of matter (e.g., stars) are converted into...

    IMPZ: a new photometric redshift code for galaxies and quasars
    We present a combined galaxy-quasar approach to template-fitting photometric redshift techniques and show the method to be a powerful one. The code (IMPZ) is...

    Individual Estimates of the Virial Factor in 10 Quasars: Implications on the Kinematics of the Broad-line Region
    Assuming a gravitational origin for the Fe iiiλλ2039-2113 redshift and using microlensing based estimates of the size of the region emitting this feature, we...

    Influence of Microlensing on the Active Galactic Nucleus Fe Kalpha Line
    We have studied the influence of gravitational microlensing on the Fe Kalpha line originating from a compact accretion disc of active galactic nuclei. We found...

    Infrared mergers and infrared quasi-stellar objects with galactic winds - I. NGC 2623: nuclear outflow in a proto-elliptical candidate
    We present the first results of a study of the morphology, kinematics and ionization structure of infrared (IR) mergers/quasi-stellar objects (QSOs) with...

    Infrared mergers and infrared quasi-stellar objects with galactic winds - II. NGC5514: two extranuclear starbursts with LINER properties and a supergiant bubble in the rupture phase
    A study of the morphology, kinematics and ionization structure of the infrared (IR) merger NGC5514 is presented. This study is based mainly on INTEGRAL two...

    Infrared mergers and infrared quasi-stellar objects with galactic winds - III. Mrk 231: an exploding young quasi-stellar object with composite outflow/broad absorption lines (and multiple expanding superbubbles)
    We present a study of outflow (OF) and broad absorption line (BAL) systems in Mrk 231, and in similar infrared (IR) quasi-stellar objects (QSOs). This study is...

    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...
