    Two Tails in NGC 3656 and the Major Merger Origin of Shell and Minor-Axis Dust Lane Elliptical Galaxies
    I report on the discovery of two faint (~26.8 R mag arcsec-2) tidal tails around the shell elliptical galaxy NGC 3656 (Arp 155). This galaxy had previously been...

    Two-dimensional line-strength maps in three well-studied early-type galaxies
    Integral field spectroscopy has been obtained for the nuclear regions of three large, well-studied, early-type galaxies. From these spectra we have obtained...
