The contribution of active galaxies to the far-infrared and submillimeter backgrounds

Abstract

We present a simple model, developed to estimate the contribution of Active Galactic Nuclei to the far--infrared background, closely linked to the AGN synthesis model for the X-ray background. According to our calculation the AGN contribution is never dominant, ranging from a few to 15 percent between 100 and 850 micron.
