    Map** the Stellar Dynamics of M31

    Using the Planetary Nebula Spectrograph, we have observed and measured the velocities for 2764 PNe in the disk and halo of the Andromeda galaxy. Preliminary analysis using a basic ring model shows a rotation c...

    Shells, Ripples and Tails

    It has been known since the early simulations of Wright (1972), and Toomre & Toomre (1972), that interactions between galaxies can give rise to quite spectacular morphological features, including spiral struct...

    Shell Formation in Ngc 474

    We present broad band photometry (B and R) of the classic shell galaxy NGC 474. Preliminary results indicate that the shells have a similar colour to and follow the same trend of colour with radius as the unde...

    Peculiar Kinematics in the Core of NGC 474

    We present absorption line profile analysis of NGC 474, an elliptical with prominent, irregular shells. Profiles are parameterized with Gauss-Hermite polynomials (van der Marel & Franx ApJ 407 1993; Rix & Whit...

    0422-476: A Shell Galaxy with Non-Aligned Shells

    0422-476, a nearly face-on S0-a galaxy, is the best example in the Malin/Carter (1983) catalogue of a shell system with shells distributed randomly “all-round” the galaxy. The shells are so bright ...

    An optical and radio survey of southern radio galaxies

    We present results from a subset of our survey of southern elliptical radio galaxies. Using VLA snapshot data and high sensitivity spectra from tile AAT Faint Object Red Spectrograph we find a strong correlati...

    Two Colour CCD Photometry of Malin-Carter Shell Galaxies

    Shells may be the result of the disruption of a small companion in the potential of a much larger galaxy (e.g., Hernquist & Quinn, 1986; Dupraz & Combes, 1985), the disturbance of a disk system in a tidal enco...

    Elliptical Galaxies with Shells

    A considerable number of otherwise normal elliptical galaxies show sharp edged, low surface brightness concentric features, often at very large radii from the parent galaxy. Features like this are visible in s...
