    Interacting binary galaxies. 7: Kinematic data for 12 disturbed ellipticals
    We have analyzed long-slit spectroscopic data for a sample of 12 tidally disturbed elliptical galaxies. The spectra were obtained with the Kitt Peak National...

    Interacting binary galaxies. V - NGC 4782/4783 (3C 278): Unbound colliders, not a supermassive pair
    The authors have determined the masses and orbital parameters for the galaxies in the strongly interacting binary NGC 4782/4783 by finding a numerical...

    Interacting binary galaxies. VI - The fast encounter of NGC 2672 and NGC 2673 (Karachentsev 175, ARP 167)
    The isolated pair of interacting ellipticals NGC 2672/2673 (Arp 167; Karachentsev 175), whose line-of-sight relative velocity is about 520 km/s, is studied...

    Interaction versus radio source generation: a CCD survey of galaxies with radio jets.
    The authors present some general results suggesting that ongoing strong interaction or merging between elliptical galaxies produces a well defined type of radio...

    Merger origin for counterrotating cores in elliptical galaxies.
    Using numerical simulations of the merger between a high- and a low-luminosity elliptical galaxy the authors show that this type of merger can result in an...

    Merger origin for the velocity and density substructure in elliptical galaxies
    The dynamics of mergers between two unequal elliptical systems was studied with self-consistent numerical simulations. Comparisons of these models to real...

    Morphological properties of radio elliptical galaxies
    A CCD imaging survey of elliptical galaxies which present radio jets is described. The photometric and morphological properties of these galaxies and their...
