*The extragalactic background light (EBL), defined here as the emission in the 0.1–1000 μm wavelength region, is one of the fundamental observational quantities in cosmology. It comprises the integrated light from resolved and unresolved extragalactic sources, and the light from any truly diffuse background, excluding the cosmic microwave background (CMB). It is therefore the repository of all energy released by nuclear and gravitational processes since the epoch of recombination. A significant fraction of this radiation is shifted by cosmic expansion and by absorption and reradiation by dust into infrared (IR) wavelengths. |
