摘要
We investigate the angular correlations in DELTAT/T on scales 10'-2-degrees which are specific for acoustic modes of perturbations in cosmic plasma before recombination. The behavior of the microwave background correlation function on scales theta = theta(b) congruent-to 40' (and 2theta(b)) allows us to determine the possible existence of these modes and to evaluate the amount of baryons in the universe and the parameter OMEGA. We propose a special method for filtering of these features in the observational data.
