    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 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...

    BASS. XXV. DR2 Broad-line-based Black Hole Mass Estimates and Biases from Obscuration
    We present measurements of broad emission lines and virial estimates of supermassive black hole masses (M BH) for a large sample of ultrahard X-ray-selected...

    BASS. XXXV. The M <SUB>BH</SUB>-σ* Relation of 105 Month Swift-BAT Type 1 AGNs
    We present two independent measurements of stellar velocity dispersions (σ ⋆) from the Ca II H+K λ3969, 3934 and Mg I b λ 5183, 5172, 5167 region (3880-5550 Å)...

    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...
