ASTROPHYSICS;
Studies from V.G. Gurzadyan and colleagues provide new data on astrophysics




"The Kolmogorov stochasticity parameter (KSP) is applied to quantify
the degree of randomness ( stochasticity) in the temperature maps of
the Cosmic Microwave Background radiation maps. It is shown that the
KSP for the WMAP5 maps is about twice as high as that of the simulated
maps for the concordance ACDM cosmological model, implying that a
randomizing effect exists that has not been taken into account by the
model," scientists in Yerevan, Armenia report (see also Astrophysics).

"As was revealed earlier, underdense regions in the large scale matter
distributions, i.e. the voids, possess hyperbolic and, hence,
randomizing properties. The degree of randomness for the Cold Spot
appears to be about twice as high as the average of the mean
temperature level spots in the sky, which supports the void nature of
the Cold Spot," wrote V.G. Gurzadyan and colleagues.

The researchers concluded: "Kolmogorov's parameter then acts as a
quantitative tracer of the voids by means of the CMB."

Gurzadyan and colleagues published their study in Astronomy &
Astrophysics (Kolmogorov stochasticity parameter measuring the
randomness in the cosmic microwave background. Astronomy &
Astrophysics, 2008;492(2):L33-L34).
