    The Bulk of the Black Hole Growth Since z ~ 1 Occurs in a Secular Universe: No Major Merger-AGN Connection
    What is the relevance of major mergers and interactions as triggering mechanisms for active galactic nuclei (AGNs) activity? To answer this long-standing...

    The bulk of the cosmic infrared background resolved by ISOCAM
    Deep extragalactic surveys with ISOCAM revealed the presence of a large density of faint mid-infrared (MIR) sources. We have computed the 15 mu m integrated...

    The bursty star formation history of the Fornax dwarf spheroidal galaxy revealed with the HST
    We present a new derivation of the star formation history (SFH) of the dSph galaxy Fornax in two central regions, characterized by unprecedented precision and...

    The Calibration of the O/H Abundance Indicators for Extragalactic H II Regions based on O II Recombination Lines
    Based on O II recombination lines we present a new calibration (called O II_{RL}) of Pagel's O_{23} indicator to determine the O/H abundance ratio in...

    The CALIFA and HIPASS Circular Velocity Function for All Morphological Galaxy Types
    The velocity function (VF) is a fundamental observable statistic of the galaxy population that is similar to the luminosity function in importance, but much...

    The CALIFA survey across the Hubble sequence. Spatially resolved stellar population properties in galaxies
    Various different physical processes contribute to the star formation and stellar mass assembly histories of galaxies. One important approach to understanding...

    The Canarias Einstein ring: a newly discovered optical Einstein ring
    We report the discovery of an optical Einstein ring in the Sculptor constellation, IAC J010127-334319, in the vicinity of the Sculptor dwarf spheroidal galaxy...
