    The star formation history of different types of dwarf galaxies
    We are going to present a new code to derive the SFH of a complex stellar population system, like a galaxy. This code has been used to obtain the SFH of six...

    The star formation history of galaxies: the role of galaxy mass, morphology and environment
    We analyse the star formation history (SFH) of galaxies as a function of present-day environment, galaxy stellar mass and morphology. The SFH is derived by...

    The star formation rates of QSOs
    We examine the far-infrared (FIR) properties of a sample of 5391 optically selected QSOs in the 0.5 < z < 2.65 redshift range down to log [νL ν, 2500(erg s -1)]...

    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 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...
