Scientific paper

On the basis of radio observations, the authors argue that ultraluminous IRAS galaxies are powered largely by star formation, and that the star formation in these galaxies occurs in both the nucleus and an extended disk. In most sources, the emission mechanism appears to be synchrotron radiation. The tight correlation between far infrared luminosity and radio luminosity observed for ordinary galaxies holds also for the extremely luminous IRAS galaxies (with L ⪆ 1011.4Lsun in the far-IR). These conclusions are based on VLA observations of ≡60 ultraluminous IRAS galaxies of known redshift. The observations were made at 6 and 20 cm wavelength, at resolutions 0.5″to 15″
