  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.
