Near-infrared integral field spectroscopy of ultraluminous infrared galaxies (ULIRGs) offers a unique way in which to view these morphologically complex galactic mergers. The Palomar Integral Field Spectrograph (PIFS), built specifically for this project, operates on the 200-inch Hale Telescope, providing moderate spectral resolution for a 5.4''\times9.6'' field of view over a wavelength range from 1--2.5 microns. The cryogenic spectrograph employs an all-aluminum, eight-element image slicer, feeding two independent spectrographs within the same dewar. Two resolution modes of R~1300 and R~550 are available, in addition to an imaging mode for photometry and target acquisition.

Morphologically interesting ULIRG candidates for integral field spectroscopy are selected from a longslit K band spectroscopic survey of 33 ULIRGs, which is a component of this thesis work. The presentation will include results from the longslit survey, aimed at searching for hidden signatures from active galactic nuclei (AGN), as well as a description of the integral field spectrograph and example ULIRG datacubes.
