Hα maps for the four objects observed at z = 3 with a spatial sampling of 0.1′′. The flux intensity, velocity dispersion σ (km s^-1), and velocity fields v maps (km s^-1) for the main component are shown. The flux intensity maps are represented on a logarithmic scale and in arbitrary flux units. All the images are centered using the Hα peak and the iso-contours of the Hα flux are over-plotted.
