we propose a systematic study of the infrared properties of blazars (bl lacertae objects and flat radio spectrum quasars) detected at high (>100mev) energies by the egret instrument on board the compton gamma ray observatory (cgro). by exploiting the full wavelength range available to iso, we intend to measure the continuum spectral energy distribution out to 200 microns and test those models wherein the high energy gamma rays are produced by inverse compton scattering of ir photons. ultimately we will combine this study with (iso) archival investigations of the ir properties of agn which have not been shown to be luminous gamma ray sources by cgro, and search for systematic differences between the two samples.

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.
