A new class of cosmological tests is proposed which examines the dependence on redshift z of the dispersion in peculiar velocities, virial mass, and mass-luminosity ratios of galactic clusters. Data on galactic clusters with redshifts up to z ≈ 2 a

Numerical simulations of the motions of stars in the gravitational fields of binary black holes with various component mass ratios have been carried out. Two models are considered: (1) the two-body problem with two fixed centers; (2) the general thre

Periodic solutions of the general free-fall three-body problem are investigated for the case of equal masses. The initial conditions are chosen on a Hill surface in form space. The use of the form space reduces the dimension of the problem and makes

The motions of the components of wide binary stars in the regular Galactic gravitational field on time scales ~1010 yr at various Galactocentric distances R0 have been studied numerically. Near the Galactic center, the influence of the bar has been t

A system of isophotes of the cosmic microwave background (CMB) is constructed for several regions on the celestial sphere using data from the Planck spacecraft. The fractal dimensionality of the isotherms is estimated to be Dc ≈ 1.78 ± 0.03. Our r

The probability of forming a Galactic hypervelocity star is estimated for the scenario of Hills, which describes the dynamical capture of one component of a binary star by the gravitational field of the supermassive black hole in the Galactic center,

The region of initial conditions for close to periodic orbits is studied in the general three-body problem with components of equal mass and zero angular momentum. A method proposed earlier, based on minimization of a functional equal to the sum of t

The goal of this study is to search for close-to-periodic orbits in the general three-body problem with equal masses and zero initial velocities. This search was carried out by scanning region D for all possible configurations of triple systems speci
