    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 - The properties of radio jet parent galaxies
    This paper presents the first systematic survey at optical wavelengths of galaxies with detected radio jets using CCD imaging. About 50 percent of the sample of...

    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...

    Interactions between massive galaxies and their satellites: probing galaxy mass distribution.
    Using the measured common distance from the observer, angular separation of a dwarf satellite from its mother galaxy and their relative radial velocities, plus...

    Interpreting asymmetric line profiles in merger remnants
    Absorption line profile asymmetries in ellipticals with peculiar core kinematics, and their role as diagnostics of mergers, are analyzed using self-consistent...

    Interstellar and intergalactic gas in the direction of SN 1993J in M81
    During the first few nights following its discovery, we observed the interstellar Ca II and Na I lines towards supernova 1993J at high spectral resolution (full...

    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...

    Structure of interacting elliptical radio galaxies
    We have used a numerical method based on elliptical fitting of isophotes to analyze the structural parameters of three pairs of elliptical galaxies containing...
