With the aim of determining the spatial distribution of the dark matter halo, we investigate two
polar ring galaxies, NGC 4262 and SPRC-7. For both galaxies, the stellar kinematics data …

… Khoperskov expresses his gratitude to nonprofit “Dynasty” foundation for financial support.
A. Moiseev also thank the Springer & EAS granted his participation on EWASS-2012. …

We provide an in-deep analysis of 25 galaxies with substantial counterrotation from
IllustrisTNG100 simulations in the stellar mass range 2�10 9 −3�10 10 M ⊙ . The counterrotation is …

With the aim to determine the spatial distribution of dark matter, we investigate the polar ring
galaxy NGC 4262. We used the stellar kinematics data for the central galaxy obtained from …

… -correlation technique to calculate the radial velocities and velocity dispersion of the stellar
component; the algorithms and software employed are similar to those described by Moiseev […

Using observational data, we build numerical N-body, hydrodynamical and combined equilibrium
models for the spiral galaxy NGC 5247. The models turn out to be unstable as regards …

… ◦ for the average angles between straight segments. … The length of such segments l, on
average, increases in direct … State University with assistance from AV Zasov and NV Tyurina. This …

With the help of high-resolution long-slit and integral-field spectroscopy observations, the
number of confirmed cases of galaxies with counterrotation is increasing rapidly. The evolution …

The dynamics of a galactic disk in a non-axisymmetric (triaxial) dark halo is studied in detail
using high-resolution, numerical, hydrodynamical models. A long-lived, two-armed spiral …

The polar ring galaxies (PRGs) represent an interesting type of peculiar systems in which
the outer matter is rotating in the plane which is roughly perpendicular to the disk of the main …
