    Mapping the properties of blue compact dwarf galaxies: integral field spectroscopy with PMAS
    Context. Blue compact dwarf (BCD) galaxies are low-luminosity, low-metal content dwarf systems undergoing violent bursts of star formation. They present a...

    Mapping the stellar population and gas excitation of MaNGA galaxies with MEGACUBES. Results for AGN versus control sample
    We present spaxel-by-spaxel stellar population fits for the ~10 000 MaNGA data cubes. We provide multiple extension fits files, nominated as MEGACUBES, with...

    Mass-metallicity relation explored with CALIFA. I. Is there a dependence on the star-formation rate?
    We studied the global and local M-Z relation based on the first data available from the CALIFA survey (150 galaxies). This survey provides integral field...

    Mass-metallicity relation of dwarf galaxies and its dependency on time: clues from resolved systems and comparison with massive galaxies
    Aims: We present a new approach to study the mass-metallicity relation and its dependency on time. Methods: We used the star formation history (SFH) derived...
