To the center of cold spot with Planck
V. G. Gurzadyan, A. L. Kashin, H. Khachatryan +3
The structure of the cold spot, of a non-Gaussian anomaly in the cosmic microwave background (CMB) sky first detected by Vielva et al. is studied using the data by Planck satellite…
Comment on the "Excess ellipticity of hot and cold spots WMAP data?" by Berntsen, E. and Hansen, F.K
A. L. Kashin, G. Yegoryan
The recent paper by Berntsen and Hansen devoted to the analysis of elliptic-ity of anisotropies in CMB maps, distorts some statements of previous studies, misses relevant papers, a…
CMB as a possible new tool to study the dark baryons in galaxies
F. De Paolis, G. Ingrosso, A. A. Nucita +7
Baryons constitute about 4% of our universe, but most of them are missing and we do not know where and in what form they are hidden. This constitute the so-called missing baryon pr…
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…
Possible detection of the M31 rotation in WMAP data
F. De Paolis, V. G. Gurzadyan, G. Ingrosso +7
Data on the cosmic microwave background (CMB) radiation by the Wilkinson Microwave Anisotropy Probe (WMAP) had a profound impact on the understanding of a variety of physical proce…
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…
