Investigating ULIRGs in the Near-Infrared: Imaging & Spectroscopy
R. Davies, A. Burston, M. Ward
Abstract
We present imaging and spectroscopic observations of 2 nearby (z<0.1) ULIRGs from a larger sample, and address the question of whether the JHK continuum colours and slope might be effective probes of the nuclear region in searches for AGN. Certainly there is evidence for significant quantities of hot dust emission at temperatures >1000K; but it may be that rather than pointing to an AGN, this instead tells us more about the environment and evolution of the star formation.
