Formation of the first halos, galaxies and magnetic fields
M. Demiański, A. Doroshkevich, T. Larchenkova
Cosmic objects with magnetic fields (quasars, radiogalaxies) are observed at redshifts (Wang et al., 2021, Fan et al., 2023, Yang et al., 2024) and more (for instance, fo…
Self similarity of the dark matter dominated objects and the shape of small scale power spectrum
M. Demiański, A. Doroshkevich
We analyzed available observational data of a sample of dark matter (DM) dominated galaxies and clusters of galaxies and we have found correlations between the virial mass, $M_{vir…
Dark matter halo formation in the multicomponent dark matter models
Vadim Semenov, Sergey Pilipenko, Andrei Doroshkevich +2
This work investigates a set of cosmological collisionless N-body simulations with featured power spectra of initial perturbations in the context of the core-cusp and satellites pr…
Simulated evolution of the dark matter large-scale structure
M. Demiański, A. Doroshkevich, S. Pilipenko +1
We analyze evolution of the basic properties of simulated large scale structure elements formed by dark matter (DM LSS) and confront it with the observed evolution of the Lyman-…
A solution of the cusp problem in relaxed halos of dark matter
E. Mikheeva, A. Doroshkevich, V. Lukash
We propose a solution of the cusp problem in framework of the standard CDM cosmology. To do this we describe the linear and nonlinear periods of halo formation by the entropy fu…
