Abstract: The cosmic infrared background (CIB) is a present day measurement of dust emission from all galaxies in the Universe. Resolving the background into individual galaxies with known redshifts constrains the output of dust obscured AGN activity and star formation over cosmic time. We average the 1mm flux densities of galaxies selected at 24μm, and resolve 31–45% of the 1mm background. These galaxies resolve 40–64% of the background at 850μm. We predict that 60–88% of the total background at 1mm comes from galaxies at z > 1.3. A numerous population of dusty, high redshift galaxies lurks below our current detection thresholds at (sub)millimeter wavelengths.
