Scientific paper

The possible existence of a near-infrared background (1 < λ < 20 μm) has been recently suggested by rocket observations. The authors discuss the effects of the interaction between such a background and extragalactic dust. Primordial dust (40 < z < 100) cannot exceed n0 < 10-21cm-3, in order to avoid a complete absorption of the background. A far-infrared diffuse radiation would be generated by dust heated by the background. Such radiation could be consistent with the recent observations of Gush in the 500 - 700 μm region.
