Central velocity dispersions, Mg-2 line indices and radial velocities for 220 E and SO galaxies are derived on the basis of intermediate resolution spectroscopy. Galaxies in the following clusters have been observed: Abell 194, Abell 539, Abell 3381,

We argue that the physical reason for the success of the Fundamental Plane and the D-n-sigma relation as distance estimators for elliptical galaxies is the existence of a relation between luminosity and mass with small intrinsic scatter. Therefore a

We study the orbital properties of dumbbell galaxies which harbor twisted radio jets. Velocity and velocity dispersion profiles for four dumbbell pairs (3C66B, 3C75, 3C449, 0326+39) are presented. We analyze optical CCD images in search of isophote o

Line strengths and their gradients in Mg, Fe, and H beta have been determined for seven elliptical and nine brightest cluster galaxies (BCGs) in order to study their stellar populations and investigate their relationship to one another. We find that

We report the discovery of neutral hydrogen in a second elliptical galaxy with shells, NGC 2865. Very Large Array images reveal an association between the neutral hydrogen (H I) and the fine structure (shells, tails, and loops) in the galaxy. Similar

Velocity dispersion profiles and rotation curves have been determined for a sample of 13 brightest duster galaxies (BCGs) in order to study their internal stellar kinematics and investigate their relationship to ellipticals. We find that BCGs general

The elliptical galaxy IC 1459 has one of the strongest counter-rotating core components of any observed elliptical. Here we present HST Planetary Camera images of the center of IC 1459. Before deconvolution, our V band images reveal a bright point so
