Nonstationary self-gravitating configurations of scalar and electromagnetic fields

Ju V Tchemarina, E G Alekseeva, A N Tsirulev +1

Mathematical modeling of gravitating configurations of physical fields is one of the priority directions of the modern theory of gravity. Most of the exact solutions constructed wi…

Anisotropic cosmological dynamics in Einstein-Gauss-Bonnet gravity: an example of dynamical compactification in 7+1 dimensions

Dmitry Chirkov, Alex Giacomini, Alexey Toporensky

We consider a particular example of dynamical compactification of an anisotropic 7+1 dimensional Universe in Einstein - Gauss - Bonnet gravity. Starting from rather general totally…

Superpotential method for chiral cosmological models connected with modified gravity

S. V. Chervon, I. V. Fomin, E. O. Pozdeeva +2

We consider the Chiral Cosmological Models (CCMs) and modified gravity theories associated with them. Generalization of the superpotential method for a general CCM with several sca…

The gravitational redshift monitored with RadioAstron from near Earth up to 350,000 km

N. V. Nunes, N. Bartel, M. F. Bietenholz +6

We report on our efforts to test the Einstein Equivalence Principle by measuring the gravitational redshift with the VLBI spacecraft RadioAstron, in an eccentric orbit around Earth…

Reconstruction of GR cosmological solutions in modified gravity theories

Igor V. Fomin, Sergey V. Chervon

We study the special class of the exact solutions in cosmological models based on the Generalized Scalar-Tensor Gravity with non-minimal coupling of a scalar field to the Ricci sca…

Wormhole as a possible accelerator of high-energy cosmic-ray particles

A. A. Kirillov E. P. Savelova

We present the simplest topological classification of wormholes and demonstrate that in open Friedmann models the genus wormholes are stable and do not require the presen…
