%0 Journal Article %T The Diverse Population of ULIRGs %A K. D. Borne %A S. Arribas %A H. Bushouse %A L. Colina %A R. A. Lucas %J Physics %D 2000 %I arXiv %X We present results from an on-going Hubble Space Telescope (HST) survey of a large sample of ULIRGs (Ultra-Luminous IR Galaxies). New ground-based observations are now being used to complement the HST data and to assist in the interpretation of these complex objects. A rich spectroscopic, morphological, and dynamical diversity is found within the ULIRG population, nearly 100% of which are merger and/or collision remnants. The consequences of this diversity may apply to the interpretation of distant submm/FIR sources and their subsequent evolution. %U http://arxiv.org/abs/astro-ph/0009361v1
