Abstract:
We present a result of cross-correlating the Infrared Astronomical
Satellite Faint Source Catalogue with the spectroscopic catalogues of
galaxies in the Fourth Data Release of the Sloan Digital Sky Survey,
the Final Data Release of the 2dF Galaxy Redshift Survey (2dFGRS) and
the Second Data Release of the 6dF Galaxy Survey. We have identified
324 ultraluminous infrared galaxies (ULIRGs) including 190 newly
discovered ULIRGs, and two hyperluminous infrared galaxies. Adding
these new ULIRGs, we increase the number of known ULIRGs by about 30
per cent. The reliability of the cross-correlation is estimated using
the likelihood ratio method.
