    Bar characterization from S4G imaging: Gaining insight into the secular evolution of disc galaxies
    The ΛCDM model predicts that galaxies originate in dark matter haloes, undergoing in their early age a process of continuous merges with other galaxies that...

    Bulge morphology of non-interacting starburst galaxies.
    The authors show, in NGC 4736, that the bulge indicates strong and radially variable ellipticity, evidence of star formation, and outflow, while the bulge of...

    Coherent star formation in spiral galaxies.
    A sample of spiral galaxies is examined, applying moments analysis to their broad-band azimuthal profiles, in order to search for evidence of coherent large...

    Colors and color gradients in bulges of galaxies
    We have obtained surface photometry in U, B, R, and I for a complete optically selected sample of 45 early-type spiral galaxies, to investigate the colors and...

    Corrugations in the discs of spiral galaxies - NGC 4244 and 5023
    The morphological characteristics of corrugations in the disk shapes of the edge-on galaxies NGC 4244 and 5023 are described to determine some of the properties...
