    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 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...
