Abstract
Within the framework of the model of the extragalactic background created earlier by the authors, the factors influencing the statistical properties of the confusion noise have been investigated. We showed the following aspects: (1) considering the large-scale structure of the Universe is an important factor; (2) gravitational lensing has no significant effect on the value of confusion noise; (3) the minimum redshift of objects that create confusion noise does not depend on the wavelength and is \({{z}_{{\min}}} \sim 0.5{-} 0.6\), the maximum redshift in the transition from 70 to 2000 µm smoothly changes from \( \sim {\kern 1pt} 4\) to \( \sim {\kern 1pt} 3\); (4) at short wavelengths (\( \simeq {\kern 1pt} 70\) µm), the main contribution to the confusion noise is made by galaxies with luminosities in the \(({{10}^{7}}{-} {{10}^{9}}){{L}_{ \odot }}\) range and at long wavelengths (650–2000 µm)—with \(L \geqslant {{10}^{{10}}}{{L}_{ \odot }}\); (5) the contribution to the confusion noise of objects with different color indices is considered; and (6) the variability of the extragalactic background created by active galactic nuclei on a time scale from 1 day to a year is noticeable at short wavelengths (70–350 μm) and manifests itself for flux densities \( \lesssim {\kern 1pt} 1\) μJy.
