Abstract

The 60-micron and far-IR luminosity functions for IRAS galaxies are presently found to be well characterized by an almost constant density/decade in luminosity, for luminosities in the 0.1 million-1 billion solar luminosities/h sq, as well as by a Gaussian dependence on log L above 1 billion solar luminosities/h sq. The shape of the luminosity function is highly insensitive to the value of both the Hubble constant and the character of local bulk flows. The far-IR luminosity density of the universe is about 1/3 that of the blue luminosity density, and is evenly divided between cool disk emission and warmer starburst emission.
