Are Young Galaxies Visible? II. The Integrated Background

In a previous publication we presented a model for the formation of galaxies and for the properties of the young galaxies. In this article the time variation of the luminosity and spectrum of the model galaxy is used to compute the integrated background radiation due to the highly redshifted starlight from all the galaxies. This background is compared with the contribution from other sources, local and extragalactic. It is concluded that in the wavelength range from S to 15 it may be possible to pick out the integrated light of the distant galaxies. The intensity is within reach of present detection techniques.
