===================================================================== ==> in this proposal, more time is being requested for gmiley.dusthzrg ===================================================================== radio-loud active galactic nuclei (agns) are unique probes of the universe, that can be observed out to large distances without bias with respect to optical or infrared properties. the best studied sample of such objects is the 3cr catalog. we are carrying out a wfpc2 snapshot imaging survey with hst and have secured excellent data for almost the entire 3cr catalog. a crucial result is the ubiquity of dust-lane galaxies, strongly reminiscent of cen a, and galaxies with chaotic dust distributions and/or disturbed morphologies. these features are readily identified out to redshift 0.5. here we propose to expand our programme gmiley.dusthzrg to obtain cam 15 micron images of all 58 3cr galaxies at redshift less than 0.5 that are visible for more than 25 percent of the rest of the iso mission. the iso data will highlight the ubiquity, role and importance of starbursts in 3cr galaxies, will elucidate the relation between various classes of agns, will allow tracing of evolutionary effects, will provide a low-z reference point for our ongoing high-z measurements, and will reveal dust emission from the brighests members of clusters in which the 3cr galaxies tend to be located.

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.
