    Study of star-forming galaxies in SDSS up to redshift 0.4. II. Evolution from the fundamental parameters: mass, metallicity and star formation rate
    Context. To understand the formation and evolution of galaxies, it is important to have a full comprehension of the role played by metallicity, star formation...

    Submillimetre compactness as a critical dimension to understand the main sequence of star-forming galaxies
    We study the interstellar medium (ISM) properties as a function of the molecular gas size for 77 infrared-selected galaxies at z ~ 1.3, having stellar masses 10...

    Super Star Clusters Versus OB Associations
    Super star clusters (M ecl > 105 M sun) are the largest stellar nurseries in our local Universe, containing hundreds of thousands to millions of young stars...

    Supersonic turbulence in giant extragalactic HII regions
    I discuss in this paper the more likely physical mechanisms that could provide the energy input for the supersonic motions observed in giant extragalactic HII...

    TAURUS observations of the velocity field in the inner zone of NGC 6946
    A two-dimensional velocity map in H-alpha of the inner 4 arc min zone of the Scd starburst galaxy NGC 6946 has been obtained using the TAURUS interferometric...

    Testing evolutionary tracks of Pre-Main Sequence stars: the case of HD113449
    Evolutionary tracks are of key importance for the understanding of star formation. Unfortunately, tracks published by various groups differ so that it is...

    The (galaxy-wide) IMF in giant elliptical galaxies: from top to bottom
    Recent evidence based independently on spectral line strengths and dynamical modelling point towards a non-universal stellar initial mass function (IMF)...

    The ATLAS3D project - XXII. Low-efficiency star formation in early-type galaxies: hydrodynamic models and observations
    We study the global efficiency of star formation in high-resolution hydrodynamical simulations of gas discs embedded in isolated early-type and spiral galaxies...
