    A study of interacting galaxies from the Arp-Madore catalog: Triggering of star formation and nuclear activity
    We present Gemini Multi-Object Spectrograph (GMOS) spectroscopic observations of 95 galaxies from the Arp & Madore (1987) catalog of peculiar galaxies. These...

    A unified model for age-velocity dispersion relations in Local Group galaxies: disentangling ISM turbulence and latent dynamical heating
    We analyse age-velocity dispersion relations (AVRs) from kinematics of individual stars in eight Local Group galaxies ranging in mass from Carina (M* ˜ 106 M⊙)...

    A very dark stellar system lost in Virgo: kinematics and metallicity of SECCO 1 with MUSE
    We present the results of VLT-MUSE (Very Large Telescope-Multi Unit Spectroscopic Explorer) integral field spectroscopy of SECCO 1, a faint, star-forming...

    A Virtual Observatory Census to Address Dwarfs Origins (AVOCADO). I. Science goals, sample selection, and analysis tools
    Context. Even though they are by far the most abundant of all galaxy types, the detailed properties of dwarf galaxies are still only poorly characterised -...

    Active star formation regions at the edge of the LMC Bar: NGC 1850 and NGC 1858
    We present UBV Johnson CCD photometry of two young clusters of the Large Magellanic Cloud (LMC), namely NGC 1850 and NGC 1858, which are located at the NW part...

    AGB and RGB stars as tracers of the early and intermediate star-formation history.
    The Milky Way and Andromeda galaxies are the largest members of the Local Group, and their evolution is affected by the evolution of their host as a whole. At...

    AGN Activity and Circumnuclear Star Formation in Nearby Galaxies
    We have selected a sample of nearby galaxies where an AGN (Seyfert or LINER) coexists with circumnuclear star formation. We use the highest spatial resolution...
