The Ultra-Luminous IR Galaxy Population
  We summarize results from an on-going Hubble Space Telescope (HST) survey of a large sample of ULIRGs (Ultra-Luminous IR Galaxies). New ground-based multi-fiber spectroscopic observations are now being obtained to complement the HST data and to assist in the interpretation of these complex objects.
