    The star formation timescale of elliptical galaxies. Fitting [Mg/Fe] and total metallicity simultaneously
    The alpha element to iron peak element ratio, for example [Mg/Fe], is a commonly applied indicator of the galaxy star formation timescale (SFT) since the two...

    The starburst galaxy NGC 7714
    Narowband H alpha imaging and long-slit optical and near-infrared spectroscopy are analyzed in a study of the starburst galaxy NGC 7714. The data indicate that...

    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...

    The striking near-infrared morphology of the inner region in M100
    New optical and near-infrared (NIR) K-band images of the inner 3 kpc region of the nearby Virgo spiral M100 (NGC 4321) display remarkable morphological changes...

    The Structure of the Underlying Stellar Host in Blue Compact Dwarf Galaxies
    Nowadays it is well established that BCDs are mostly old systems, as the vast majority of them have an extended low-surface brightness (LSB) stellar host...

    The synchronized dance of the magellanic clouds' star formation history
    We use the SMASH survey to obtain unprecedented deep photometry reaching down to the oldest main-sequence turn-offs in the colour-magnitude diagrams (CMDs) of...

    The truncation of the disk of NGC 4565. Detected up to z = 4 kpc, with star formation, and affected by the warp
    Context. The hierarchical model of galaxy formation suggests that galaxies are continuously growing. However, our position inside the Milky Way prevents us from...

    The ultraviolet to far-infrared spectral energy distribution of star-forming galaxies in the redshift desert
    We analyse the rest-frame ultraviolet (UV) to near-infrared (near-IR) spectral energy distribution (SED) of Lyman-break galaxies (LBGs), star-forming (SF) BzK...

    The universal variability of the stellar initial mass function probed by the TIMER survey
    The debate about the universality of the stellar initial mass function (IMF) revolves around two competing lines of evidence. While measurements in the Milky...
