    H II regions, morphology and star formation in disc galaxies.

    The distribution and morphology of H II regions in the discs of spirals has been examined in great detail for a set of objects imaged in Hα. In those with...

    Near-infrared mapping of spiral galaxies. I - The SB galaxy NGC 2841 - Annular structure in the young disc component

    NGC 2841 has been mapped in the J and K near-infrared bands out to some 10 kpc from its center. Maps and radial profiles in micron(J), micron(K) and J-K are...

    Photometric separation of the bulge and disc components of spirals using CCD imaging

    High-resolution CCD images are presented of a sample of spiral galaxies, in infrared photometric bands, obtained at the Cassegrain focus of the 1 m Jacobus...

    Photometric Signature of Ultraharmonic Resonances in Barred Galaxies

    Bars may induce morphological features, such as rings, through their resonances. Previous studies suggested that the presence of "dark gaps," or regions of a...

    Secondary Infall in the Seyfert’s Sextet: A Plausible Way Out of the Short Crossing Time Paradox

    We used integral field spectroscopy from CALIFA DR3 and multiwavelength publicly available data to investigate the star formation histories of galaxies in the...
