Abstract
We have made R band images and photometry of 9 ultraluminous infrared galaxies, 5 of which show no apparent signs of interaction. We find th at the 5 latter radiate more than 50 times in the far-infrared than th ey do in the optical. These highly obscured objects could be the end p roducts of collisions between gas rich galaxies in a final phase of me rger evolution.
