we have recently observed several gravitationally lensed objects with scuba on the jcmt. one of them shows very strong submm flux, comparable to iras f10214+4724 and the cloverleaf quasar. the object is very likely a dusty high redshift infrared galaxy or quasar, but its redshift has not yet been measured because of an extremely red optical spectrum. hst observations in the near-ir reveal a 1 diameter einstein ring. we wish to obtain a full, broadband spectrum across the ir to determine this object.s spectral energy distribution and possibly get a rough estimate of its redshift. this appears to be a member of a rare class of observable high-redshift ir-galaxies/quasars which warrants follow-up with iso before the mission ends.

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.
