The analysis of a complete sample of about 2000 galaxies surveyed in the radio continuum and in the far-infrared (FIR) shows that nonthermal radio and thermal FIR luminosities of spiral galaxies are closely correlated, suggesting that they have a common origin. Direct evidence is shown that the mean radio and FIR luminosities of spiral galaxies are a function of the Hubble type. This strengthens the hypothesis that star formation is the relevant process that provides the energy sources for both types of radiation. 23 references.
