Abstract:
The influence of the observed relict vacuum energy on the fluctuations
of CMBR going through cosmological matter condensations is studied in
the framework of the Einstein-Strauss-de Sitter vakuola model. It is
shown that refraction of light at the matching surface of the vakuola
and the expanding Friedman universe can be very important during
accelerated expansion of the universe, when the velocity of the matching
surface relative to static Schwarzchildian observers becomes
relativistic. Relevance of the refraction effect for the temperature
fluctuations of CMBR is given in terms of the redshift and the angular
extension of the fluctuating region.
