Description:
We present a new, large sample of ultraluminous (L60>1011.4L☉
for H0=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% 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.
