The effects of dust and metallicity evolution on the cosmic infrared background

Abstract
The contribution of galaxies to the cosmic infrared background (CIB) is a complicated function of their star formation history, the evolution of their metallicity and dust content, and details of the transfer of the stellar energy output through the dusty interstellar medium. We present preliminary results of models examining the effects of dust evolution on the spectral appearance of galaxies, in order to understand their evolving contribution to the CIB.
