Description:
We present a new, large sample of ultraluminous
(L_60_>10^11.4^L_{sun}_ for H_0_=100km/s/Mpc) IRAS galaxies selected
for the IRAS Faint Source Survey using a novel optical far-infrared
colour selection criterion. Our technique proves to be very successful
in selecting luminous galaxies, and we present data on 91
ultraluminous objects, of which 65 are newly discovered. Using our
redshift spectra and information from the literature we find that at
least 35 per cent of these objects are likely to contain an AGN-type
central engine. We also find that purely IR-based techniques for
determining the presence of an AGN in these objects are unreliable.
