we propose to investigate the mid and far ir spectral energy distributions of powerful radio sources at intermediate and high redshifts. the goals of the program are to determine the luminosities and spectral energy distributions of radio loud quasars and radio galaxies. this will allow us to examine the evolution of dust in agns, the similarities and differences between radio galaxies and quasars, and the contribution of evolved stars to the near ir spectra of radio galaxies at z = 2. our sample is a combination of a sub-set of the complete 3cr and high redshift radio galaxies and quasars from the mrc/1jy survey. the sources have been selected for high ecliptic latitude and low cirrus brightness, i.e. so as to lie in the darkest regions of the fir sky. this program will provide one of the best opportunities to explore the mid and fir properties of radio sources over a wide range of redshifts.

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.
