CO in infrared luminous galaxies

Abstract

There has been considerable recent interest in the properties of infrared galaxies due to the discovery by the Infrared Astronomical Satellite (IRAS) of a class of luminous galaxies which emit the bulk of their energy in the far-infrared (Houck et al. 1984; Soifer et al. 1984). Ground-based studies of these infrared luminous galaxies have shown that they are a substantial component of the local universe (z ~ 0.1) with a space density at luminosities above 1011 L⊙ (H_o = 75 km s^(-1)Mpc^(-1)) exceeding that of Seyfert galaxies and quasars (Soifer et al. 1986).
