PHOTOMETRY OF GALAXIES IN DEEP RADIO=SELECTED SURVEYS

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 subsample of 50 galaxies of our original sample which reside in the deep field of the survey, be upgraded. we propose to carry out farinfrared 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 subarea of 0.5 square degree of our original survey. to this limit, a significant number of ultraluminous infrared galaxies and seyferts are expected to be detected. we propose to investigate if the absence of highredshift galaxies from deep optical surveys is due to dust extinction of starforming ellipticals. also, farinfrared observations will be used to estimate the space densities of different classes of objects in deep radio surveys and to investigate if the radio60 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 farinfrared surveys will also be studied. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
