we wish to investigate the dust in three protypical galaxies which we have shown to have optical emission line associated morphologically with radio jets. because in such objects nonthermal jets coexist and interact with the thermal ism, they provide a unique set of diagnostics for studying the properties of active galaxies. such jet/ism galaxies are therefore more informative probes than normal radio galaxies. although jet/gas associations are rare at low redshifts, for z > 0.1 they are frequent. hence, nearby examples of such phenomena are also likely to be unique laboratories for studying processes which occur frequently in the early universe. in contrast to high-redshift radio galaxies, the low-redshift cases can be spatially resolved with isocam. we therefore wish to study the best low-redshift examples. the main aim of this proposal are to use isocam to obtain information about the morphologies, masses and physical conditions of the warm dust in these objects. the results, when compared with existing data, will provide important information about the properties of the ism in such galaxies and will constrain the jet momentum and energetics. all our targets, except 3c 277.3 have been detected by iras. for 3c 277.3 we shall also make a short observation at four bands with isophot to determine the spectrum of the cold dust component.

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.
