    The StEllar Counterparts of COmpact high velocity clouds (SECCO) survey. I. Photos of ghosts
    We present an imaging survey that searches for the stellar counterparts of recently discovered ultra-compact high-velocity H i clouds (UCHVC). It has been...
  • Publication
    The StEllar Counterparts of COmpact high velocity clouds (SECCO) survey. II. Sensitivity of the survey and the atlas of synthetic dwarf galaxies
    The searching for StEllar Counterparts of COmpact high velocity clouds (SECCO) survey is devoted to the search for stellar counterparts within ultra compact...

    The stellar halo in Local Group Hestia simulations. I. The in situ component and the effect of mergers
    Theory suggests that mergers play an important role in shaping galactic discs and stellar haloes, which was observationally confirmed in the Milky Way (MW)...
  • Publication
    The stellar halo in Local Group Hestia simulations. II. The accreted component
    Recent progress in understanding the assembly history of the Milky Way (MW) is driven by the tremendous amount of high-quality data delivered by Gaia (ESA)...

    The stellar halo in Local Group Hestia simulations. III. Chemical abundance relations for accreted and in situ stars
    Stellar chemical abundances and kinematics provide key information for recovering the assembly history of galaxies. In this work we explore the chemo-chrono...

    The Stellar Halo of the Spiral Galaxy NGC 1560
    We report on the detection of a stellar halo around NGC 1560, a 109 M ⊙ spiral galaxy member of the Maffei group. We obtained deep images in the r- and i-bands...

    The stellar host in blue compact dwarf galaxies. The need for a two-dimensional fit
    Context: The structural properties of the low surface brightness stellar host in blue compact dwarf galaxies are often studied by fitting r1/n models to the...
  • Publication
    The stellar host in star-forming low-mass galaxies: Evidence for two classes
    Context. The morphological evolution of star-forming galaxies provides important clues to understand their physical properties, as well as the triggering and...
