Detection of X-ray galaxy clusters based on the Kolmogorov method
V. G. Gurzadyan, F. Durret, T. Ghahramanyan +3
The detection of clusters of galaxies in large surveys plays an important part in extragalactic astronomy, and particularly in cosmology, since cluster counts can give strong const…
Degree of randomness: numerical experiments for astrophysical signals
V. G. Gurzadyan, T. Ghahramanyan, S. Sargsyan
Astrophysical and cosmological signals such as the cosmic microwave background radiation, as observed, typically contain contributions of different components, and their statistica…
A weakly random Universe?
V. G. Gurzadyan, A. E. Allahverdyan, T. Ghahramanyan +7
The cosmic microwave background (CMB) radiation is characterized by well-established scales, the 2.7 K temperature of the Planckian spectrum and the amplitude of the temp…
Plane-mirroring anomaly in the cosmic microwave background maps
V. G. Gurzadyan, T. Ghahramanyan, A. L. Kashin +5
The plane-mirror symmetry previously noticed in the Cosmic Microwave Background (CMB) temperature anisotropy maps of Wilkinson Microwave Anisotropy Probe is shown to possess certai…
Kolmogorov cosmic microwave background sky
V. G. Gurzadyan, A. E. Allahverdyan, T. Ghahramanyan +7
A new map of the sky representing the degree of randomness in the cosmic microwave background (CMB) temperature has been obtained. The map based on estimation of the Kolmogorov sto…
Large Scale Plane-Mirroring in the Cosmic Microwave Background WMAP5 Maps
V. G. Gurzadyan, A. A. Starobinsky, T. Ghahramanyan +5
We continue investigation of the hidden plane-mirror symmetry in the distribution of excursion sets in cosmic microwave background (CMB) temperature anisotropy maps, previously not…
