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…
