On the detection of point sources in Planck LFI 70 GHz CMB maps based on cleaned K-map
H. G. Khachatryan, A. L. Kashin, E. Poghosian +1
We use the Planck LFI 70GHz data to further probe point source detection technique in the sky maps of the cosmic microwave background (CMB) radiation. The method developed by Tegma…
Planck's confirmation of the M31 disk and halo rotation
F. De Paolis, V. G. Gurzadyan, A. A. Nucita +8
Planck's data acquired during the first 15.4 months of observations towards both the disk and halo of the M31 galaxy are analyzed. We confirm the existence of a temperature asymmet…
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…
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…
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…
Kolmogorov analysis detecting radio and Fermi gamma-ray sources in cosmic microwave background maps
V. G. Gurzadyan, A. L. Kashin, H. G. Khachatryan +4
The Kolmogorov stochasticity parameter is shown to act as a tool to detect point sources in the cosmic microwave background (CMB) radiation temperature maps. Kolmogorov CMB map con…
Exploring the cosmic microwave background as a composition of signals with Kolmogorov analysis
S. Mirzoyan, E. Poghosian
The problem of separation of different signals in the Cosmic Microwave Background (CMB) radiation using the difference in their statistics is analyzed. Considering samples of seque…
The power spectrum of the cosmic microwave background Kolmogorov maps: possible clue to correlation of voids
V. G. Gurzadyan, A. L. Kashin, H. G. Khachatryan +4
The power spectrum is obtained for the Kolmogorov stochasticity parameter map for WMAP's cosmic microwave background (CMB) radiation temperature datasets. The interest for CMB Kolm…
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…
