    Little impact of mergers and galaxy morphology on the production and escape of ionizing photons in the early Universe
    Compact, star-forming galaxies with high star formation rate surface densities (Σ SFR) are often efficient Lyman continuum (LyC) emitters at z ≤ 4.5, likely...

    LITTLE THINGS in 3D: robust determination of the circular velocity of dwarf irregular galaxies
    Dwarf irregular galaxies (dIrrs) are the smallest stellar systems with extended H i discs. The study of the kinematics of such discs is a powerful tool to...
  • Publication
    Local anticorrelation between star formation rate and gas-phase metallicity in disc galaxies
    Using a representative sample of 14 star-forming dwarf galaxies in the local Universe, we show the existence of a spaxel-to-spaxel anticorrelation between the...

    Local Cosmology from Isolated Dwarfs: the derivation of star formation histories.
    The color-magnitude diagram (CMD) is the most powerful tool to derive quantitative star formation histories (SFHs) of complex stellar systems which host...

    Local Cosmology from Isolated Dwarfs: variable stars from the LCID project.
    During Cycle 14 a total of 113 HST orbits were secured to observe five isolated dwarf galaxies, namely Tucana, LGS3, LeoA, IC1613, and Cetus. The aim of the...

    Local Group Galaxies: Abundances in NGC 3109
    We present preliminary results of VLT spectroscopy follow-up of Planetary Nebulae (PNe) and HII regions in the dwarf Irregular galaxy NGC 3109. In total we have...

    Local Tadpole Galaxies
    Tadpole galaxies have a giant star-forming region at the end of an elongated intensity distribution. Here we use Sloan Digital Sky Survey data to determine the...
  • Publication
    Local Tadpole Galaxies: Dynamics and Metallicity
    Tadpole galaxies, with a bright peripheral clump on a faint tail, are morphological types unusual in the nearby universe but very common early on. Low mass...

    Local variations of the stellar velocity ellipsoid - II. The effect of the bar in the inner regions of Auriga galaxies
    Theoretical works have shown that off-plane motions of bars can heat stars in the vertical direction during buckling but is not clear how do they affect the...
