    2D surface brightness modelling of large 2MASS galaxies II: the role of classical bulges and pseudobulges on galaxy scaling relations and its implication for supermassive black hole formation
    We have generated 2D-multicomponent surface brightness (SB) modelling for 100 galaxies in the Large Galaxy Atlas (LGA) together with 19 nearby cD galaxies using...

    A galaxy which outshines the rest
    Gas is essential to the process of forming a galaxy. During the first stages the amount of gas present determines the number of stars which will be in the...

    A refined sub-grid model for black hole accretion and AGN feedback in large cosmological simulations
    In large-scale cosmological hydrodynamic simulations simplified sub-grid models for gas accretion on to black holes and AGN feedback are commonly used. Such...

    Absence of radio-bright dominance in a near-infrared selected sample of red quasars
    Context. The dichotomy between red and blue quasars is still an open question. It is debated whether red quasars are simply blue quasars that are observed at...

    Active Galactic Nuclei Feedback and the Origin and Fate of the Hot Gas in Early-type Galaxies
    A recent determination of the relationships between the X-ray luminosity of the ISM (L X) and the stellar and total mass for a sample of nearby early-type...

    AGILE, Fermi, Swift, and GASP/WEBT multi-wavelength observations of the high-redshift blazar 4C +71.07 in outburst
    Context. The flat-spectrum radio quasar 4C +71.07 is a high-redshift (z = 2.172), γ-loud blazar whose optical emission is dominated by thermal radiation from...
