Luminous infrared galaxies were discovered in small numbers
about three decades ago. Their discovery as a large class of objects
was made by the IRAS satellite
in 1983. They emit the bulk of their radiation
in the infrared, and may represent evolutionary stages of two merging elliptical galaxies to a quasar.
The dominant powering mechanism of luminous infrared galaxies
has been shown to be either starburst activity or
Active Galactic Nuclei (AGN) activity, and sometimes both.
We carried out an optical and radio study of 285 infrared
galaxies over a range of
luminosities to answer the following questions:
