Description we propose to obtain the infrared spectral energy distributions of 15 gamma-ray blazars from the second egret catalog which are not included in the guaranteed or approved open time proposals. this increases the size of a statistically complete sample from 26 to 41 objects. the infrared emission in blazars is dominated by highly beamed synchrotron radiation from a relativistic jet. photons from the peak of the synchrotron energy output (in the infrared for most high-luminosity blazars) or from an external radiation field are inverse-compton scattered to gamma-ray energies by the synchrotron-emitting electrons. the infrared spectral shape is vital to constraining models of the broad-band emission in this objects by characterizing the physical parameters of the relativistic charged particles which do the scattering.

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.
