One of the main objectives of modern cosmology is to explain the origin and evolution of
cosmic structures at different scales. The principal force responsible for the formation of such …

In the framework of the concordance cosmological model, the first-order scalar and vector
perturbations of the homogeneous background are derived in the weak gravitational field limit …

In the presence of the gravitational field, the energy density of matter no longer coincides
with its mass density. A discrepancy exists, of course, also between the associated power …

We study a universe filled with dust-like matter in the form of discrete inhomogeneities (eg,
galaxies and their groups and clusters) and two sets of perfect fluids with linear and nonlinear …

We study the effect of box size on the matter power spectrum obtained via cosmological N-body
simulations. Within the framework of the cosmic screening approach, we show that the …

We make a generalization of a self-consistent first-order perturbation scheme, being suitable
for all (sub-horizon and super-horizon) scales, which has been recently constructed for the …

In this paper, we consider dynamical behavior of astrophysical objects such as galaxies and
dwarf galaxies taking into account both the gravitational attraction between them and the …

Without exceeding the limits of the conventional ΛCDM paradigm, we argue for Yukawa law
of interparticle interaction as the law of gravitation in the real expanding inhomogeneous …

We investigate the backreaction of nonlinear perturbations on the global evolution of the
Universe within the cosmic screening approach. To this end, we have considered the second-…

We calculate the present expansion of our Universe endowed with relict colored objects—quarks
and gluons—that survived hadronization either as isolated islands of quark-gluon" …
