Analysis of the Merger Remnant

Is the merger remnant in the centre of the cluster a giant elliptical or cD galaxy? We measured the shape of the central galaxy, the surface density and velocity dispersion profiles along different lines of sight to answer this. We also measured the three-dimensional structure and kinematics of the stars and dark matter for comparison to interpretations of the projected data.
