broad line radio galaxies (blrgs) display properties in between those of radio-loud quasars and narrow line radio galaxies. iras far-infrared energy distributions of some blrgs indicate the presence of a hot dust component, whereas optical spectra of several blrgs have revealed an unusually bright starlight component. we wish to use isophot to observe a sample of broad line radio galaxies in order to examine this trend further. the resulting data will be used to investigate (circum)nuclear star formation in blrgs and to address the place of the blrg class in unified schemes for radio-loud objects.

Mission Description
The Infrared Space Observatory (ISO) was the world's 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.
