Description
  • Vliv pozorované reliktní vakuové energie na fluktuace v mikrovlnném kosmickém pozadí probíhající skrze kondenzaci kosmologické hmoty je studován v rámci Einsteinova-Straussova-de Sitterova vakuolového modelu. Ukazujeme, že lom světla na povrchu spojujícím vakuolu a expandující Friedmanův vesmír může být velmi důležitý během zrychlené expanze vesmíru, pokud rychlost tohoto povrchu vzhledem ke statickým schwarzschildovým pozorovatelům bude relativistická. Význam efektu lomu pro vývoj teplotních fluktuací mikrovlnného kosmického pozadí je vyjádřen prostřednictvím rudého posuvu a úhlové velikosti fluktujícího regionu. (cs)
  • 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.
