    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...

    Dynamical simulations of the interacting galaxies in the NGC 520/UGC 957 system

    Numerical simulations of the interacting galaxies in the NGC 520/UGC 957 system are presented. Two sets of models were produced to investigate the postulated...

    From Naked Spheroids to Disky Galaxies: How Do Massive Disk Galaxies Shape Their Morphology?

    We investigate the assembly history of massive disk galaxies and describe how they shape their morphology through cosmic time. Using SHARDS and HST data, we...

    Further evidence of continuity between elliptical and disc galaxies

    The behavior of the isophotes of the E galaxies in a new photometric sample of 33 early-type galaxies belonging to the Virgo cluster (Caon) is compared to that...

    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...
