we propose to survey in the oi line seven high redshift iras sources selected so their redshift places the oi line in the most sensitive part of the lws range, namely 100<lambda<180, translating to 0.58<z<1.5. while most of these sources are classified as quasars, their infrared emission suggests a substantial interstellar medium, which we could partially characterize using the oi fine structure line. we estimate the oi line should be detectable typically in one hour of integration if its relative intensity is comparable to starbursts values. in all cases, we expect to place interesting upper limits on the warm and dense photo-dissociated ism in these objects.

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.
