we were awarded 41 hours of priority 3 time for this proposal in the first iso call, and we are here requesting that this priority, for a sub-sample of 50 galaxies of our original sample which reside in the deep field of the survey, be upgraded. we propose to carry out far-infrared observations of a complete and homogeneous sample of 50 galaxies selected in radio (1.4 ghz) wavelengths to a flux limit of s(1.4) virgul 0.3 mjy, covering a sub-area of 0.5 square degree of our original survey. to this limit, a significant number of ultra-luminous infrared galaxies and seyferts are expected to be detected. we propose to investigate if the absence of high-redshift galaxies from deep optical surveys is due to dust extinction of starforming ellipticals. also, far-infrared observations will be used to estimate the space densities of different classes of objects in deep radio surveys and to investigate if the radio-60 micron relation, found for local galaxies, holds for the fainter, more distant sources as well. nature of the excess population, detected in in optical and far-infrared surveys will also be studied.

Mission Description
The Infrared Space Observatory (ISO) was the worlds first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
