from the spectacularly sharp discontinuities observed in the radio continuum and lyman-alpha images of several radio galaxies we have very recently argued that these ellipticals are surrounded by dusty superdisks, extended on virgul100 kpc scale. this newly identified feature can play a crucial role in the models of radio galaxy formation. iso offers good prospects of providing their first ever images in emission, which are indispensable for understanding this phenomenon. quite likely, the reported detection of the z = 3.8 radio galaxy 4c41.17 in the rest-frame far-infrared using the iram and jcmt telescopes dishes corresponds to the superdisk inferred by us in this very distant galaxy. we propose a deep imaging in mid/far-ir of two best superdisk targets associated with classical radio galaxies at z virgul0.1 .

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.
