[55.04] Rest Frame Optical Spectroscopy of Hyperluminous Infrared Galaxies.

E. L. Ryan (SIRTF Science Center)

Like ULIRGs, Hyperluminous Infrared Galaxies (HLIRGs) appear to have emission components from both AGN and Starburst activity. Because many HLIRGs are at z > 0.75, use of common optical spectral diagnostics is difficult, and as a result, most analysis has been done using submm data. I will present the first rest frame optical spectra of HLIRGs in this poster. With this data taken at UKIRT, I will present a preliminary analysis of the spectral contributions by AGN and Starburst activity within these galaxies.
