AbstractDeep charge-coupled device imaging has been used to identify a number of IRAS (Infrared Astronomical Satellite) blank field sources with distant galaxies, and indicates that most high-latitude unidentified IRAS point sources have an extragalactic origin. The present sample of galaxies seems to include some with the largest known ratios of IR-to-optical luminosity, with values of L(IR)/L(B) ranging upwards of 200. A redshift obtained for one source, 0422+009, indicates that this object has ~35 times the absolute IR luminosity of the starburst galaxy M82.
