Is there a need for dark matter in galaxies?
I. K. Rozgacheva, A. A. Agapov
We present arguments indicating that galaxies and their clusters should be considered as open developing systems. Galaxies interact with the intergalactic medium and are not in a v…
On a problem of dark matter: A centrally symmetric distribution of a pseudoscalar field in the general relativity
I. K. Rozgacheva, A. A. Agapov
A precise solution of the general relativity equations for centrally symmetric distribution of a pseudoscalar field with U(1) symmetry is presented. It is found that energy density…
Wavelet-analysis of series of observations of relative sunspot numbers. The dependence of the periods of cyclic activity on the time at different time scales
A. A. Borisov, E. A. Bruevich, V. V. Bruevich +2
We applied the method of continuous wavelet-transform to high-quality time-frequency analysis to the sets of observations of relative sunspot numbers. Wavelet analysis of these dat…
On physical vacuum as an unobservable system
I. K. Rozgacheva, A. A. Agapov
Modern astronomical observations in cosmology provide increasingly strong evidence that the expansion of the Universe is accelerating. Explanations of the cosmic acceleration withi…
Can Rossby waves explain the cyclic magnetic activity of the Sun and solar-type stars?
E. A. Bruevich, I. K Rozgacheva
Magnetic activity is a global property of the Sun; the complex processes of solar activity are connected with the solar magnetic fields. For solar-type stars and the Sun magnetic a…
The anisotropy properties of a background radiation in the fractal cosmological model
I. K. Rozgacheva, A. A. Agapov
We consider the anisotropy properties of a background radiation in the fractal cosmological model. The space of this model includes self-similar domains. The metric tensors of any…
Cycles of the magnetic activity of the Sun and solar-type stars and simulation of their fluxes
E. A. Bruevich, I. K. Rozgacheva
The application of the Wavelet analysis and Fourier analysis to the dataset of variations of radiation fluxes of solar-like stars and the Sun is examined. In case of the Sun the wa…
On the global magnetic activity and dynamo of the Sun and solar-type stars
E. A. Bruevich, I. K. Rozgacheva
The activity of the Sun as a result of cyclic changes of the global magnetic field is studied. As a consequence of the analysis of magnetic activity of solar-type stars the followi…
Fractal properties of the large-scale structure
I. K. Rozgacheva, A. A. Borisov, A. A. Agapov +2
The statistical analysis and the spherical wavelet analysis of the SDSS DR7 quasars distribution and of the WMAP CMB anisotropy are performed. They revealed the qualitative agreeme…
The fractal cosmological model
I. K. Rozgacheva, A. A. Agapov
The fractal cosmological model which accounts for observable fractal properties of the Universe's large-scale structure is constructed. In this framework these properties are conse…
Fractal properties of SDSS quasars
I. K. Rozgacheva, A. A. Agapov
The distribution of SDSS quasars is described. The dependence of observational number of quasars within distances to an observer less than r on distance r is found to be the power…
Investigation of Properties of the Intercluster Medium Rich Clusters of Galaxies
I. K. Rozgacheva, I. B. Kuvshinova
The statistical analysis of properties of 213 rich clusters of galaxies is performed. The existence of correlations between the X-ray luminosity and the temperature of the intraclu…
