Reports from V.G. Gurzadyan and co-researchers add new data to
research in astrophysics
"The power spectrum is obtained for the Kolmogorov stochasticity
parameter map for WMAP's cosmic microwave background (CMB) radiation
temperature datasets," investigators in Yerevan, Armenia report (see
also Astrophysics).
"The interest for CMB Kolmogorov map is that it can carry direct
information about voids in the matter distribution, so that the
correlations in the distribution of voids have to be reflected in the
power spectrum. Although limited by the angular resolution of the
WMAP, this analysis shows the possibility of acquiring this crucial
information via CMB maps," wrote V.G. Gurzadyan and colleagues.
The researchers concluded: "Even the already obtained behavior, some
of which is absent in the simulated maps, can influence the
development of views on the void correlations at the large-scale web
formation."
Gurzadyan and colleagues published their study in Astronomy &
Astrophysics (The power spectrum of the cosmic microwave background
Kolmogorov maps: possible clue to correlation of voids. Astronomy &
Astrophysics, 2009;506(3):L37-L40).
