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...

Context. We continue to study star formation in dwarf galaxies located in nearby clusters. Aims: Known physical and chemical relations outlining the formation...

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...

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...

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 represent a rapid growth phase of both star formation and massive galaxies. Mapping SMGs in galaxy protoclusters provides key insights...

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 (SSCs) are young massive objects typically observed in starburst galaxies. They consist of millions of stars occupying volumes only several...

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...
