Abstract:

The forty ultraluminous galaxies in the IRAS Bright Galaxy Sample of sources were mapped with 0.25 second resolution at 8.44 Grigahertz. Twenty five contain diffuse radio sources. These are almost certainly starburst galaxies. The IRAS flux densities for all galaxies detected in the Faint Source Survey have been obtained. The data contains a total of 1544 galaxies. The detection rate in the FSS improves substantially by a factor of three or more for the short wavelength bands at 12 and 25 microns. This sample will form the basis for studies of the far infrared properties of optically selected galaxies.
