    Studying old populations with RR Lyrae Variables in the Local Group
    We want to study the characteristics and the physical extent of the old populations in a sample of Local Group galaxies in different environments, from the dSph...

    Studying star forming dwarf galaxies in Abell 779, Abell 1367, Coma, and Hercules clusters
    Context. We continue to study star formation in dwarf galaxies located in nearby clusters. Aims: Known physical and chemical relations outlining the formation...

    Sub-arcsec mid-IR observations of NGC 1614: Nuclear star formation or an intrinsically X-ray weak AGN?
    We present new mid-infrared (mid-IR) N-band spectroscopy and Q-band photometry of the local luminous IR galaxy NGC 1614, one of the most extreme nearby...

    Subarcsecond Emission in Seyfert Galaxies: The Nuclear Component in the L and M Bands
    We present deep L- (3.8 μm) and M- (4.7 μm) band imaging with the Infrared Spectrometer and Array Camera (ISAAC) on the ESO Very Large Telescope (VLT) with...

    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...

    Submillimetre galaxies in two massive protoclusters at z = 2.24: witnessing the enrichment of extreme starbursts in the outskirts of HAE density peaks
    Submillimetre galaxies represent a rapid growth phase of both star formation and massive galaxies. Mapping SMGs in galaxy protoclusters provides key insights...

    Sulphur and zinc abundances in Galactic halo stars revisited
    Aims:Based on a new set of sulphur abundances in very metal-poor stars and an improved analysis of previous data, we aim at resolving current discrepancies on...

    Super star clusters and their emission lines
    Super star clusters (SSCs) are young massive objects typically observed in starburst galaxies. They consist of millions of stars occupying volumes only several...

    Super star clusters in Hii galaxies
    We summarize our results based on observations with the NIRI camera on the Gemini North telescope of three Hii galaxies (Mrk 36, UM 408 and UM 461), obtained to...
