We present high spatial resolution H and K'-band images of a complete sample of ultraluminous infrared galaxies selected to have warm mid-infrared colors known to be characteristic of active galaxies. The extended underlying galaxy is detected in each system, as are tidal features and many of the star-forming knots seen at optical wavelengths. While some of these knots have a considerable near-infrared excess, we show that they are likely to have bolometric luminosities more similar to that ofdoi:10.1086/306737 fatcat:5zm2s7fnybaevlfkn5b4sbrq5u
