    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...

    Black hole masses for 14 gravitationally lensed quasars
    Aims: We have estimated black hole masses (M BH) for 14 gravitationally lensed quasars using Balmer lines; we also provide estimates based on MgII and CIV...

    Capturing dual AGN activity and kiloparsec-scale outflows in IRAS 20210+1121
    The most standard scenario for the evolution of massive galaxies across cosmic time assumes a correspondence based on the interplay between active galactic...

    CEERS Key Paper. II. A First Look at the Resolved Host Properties of AGN at 3 &lt; z &lt; 5 with JWST
    We report on the host properties of five X-ray-luminous active galactic nuclei (AGN) identified at 3 < z < 5 in the first epoch of imaging from the Cosmic...
