Scientific paper
The use of more sensitive radio telescopes to identify individual structural features in the distribution of Delta T/T over the celestial sphere, and thus obtain information on the fine-scale anisotropy of the cosmic background radiation, is discussed. By analyzing the statistical parameters of pips in the microwave background temperature fluctuations due to regions which had anomalously strong metric perturbations during the hydrogen recombination era, evidence on the correlation properties of that anisotropy can be gained even if the anisotropy is two to three times weaker than the prevailing noise levels of instrumental, atmospheric, galactic, and extragalactic origin.
