New features of parallel implementation of N-body problems on GPU
S. S. Khrapov, S. A. Khoperskov, A. V. Khoperskov
This paper focuses on the parallel implementation of a direct -body method~(particle-particle algorithm) and the application of multiple GPUs for galactic dynamics simulations.…
The evolution of hydrocarbon dust grains in the interstellar medium and its influence on the infrared spectra of dust
M. S. Murga, S. A. Khoperskov, D. S. Wiebe
We present evolutionary calculations for the size and aromatization degree distributions of interstellar dust grains, driven by their destruction by radiation, collisions with gas…
Restructuring and destruction of hydrocarbon dust in the interstellar medium
M. S. Murga, S. A. Khoperskov, D. S. Wiebe
A model of key processes influencing the evolution of a hydrocarbon grain of an arbitrary size under astrophysical conditions corresponding to ionized hydrogen regions (HII regions…
Transport of charged dust grains into the galactic halo
S. A. Khoperskov, Yu. A. Shchekinov
We develop a 3D dynamical model of dust outflows from galactic discs. The outflows are initiated by multiple SN explosions in a magnetized interstellar medium (ISM) with a gravitat…
Interaction between collisionless galactic discs and nonaxissymmetric dark matter haloes
A. V. Khoperskov, S. A. Khoperskov, A. V. Zasov +2
Using -body simulations (), we examine how a non-axisymmetric dark halo affects the dynamical evolution of the structure in collisionless (stellar) discs. We…
Global Gravitationally-Organized Spiral Waves and the Structure of NGC 5247
S. A. Khoperskov, A. V. Khoperskov, I. S. Khrykin +5
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 towards spira…
The interaction of dark matter cusp with the baryon component in disk galaxies
S. A. Khoperskov, B. M. Shustov, A. V. Khoperskov
In this paper we examine the effect of the formation and evolution of the disk galaxy on the distribution of dark halo matter. We have made simulations of isolated dark matter (DM)…
Dynamics of galactic disks in the nonaxisymmetric dark halo
Alexander Khoperskov, Mikhail Eremin, Sergej Khoperskov +2
The results of numerical simulations of the dynamics of galactic disks, which are submerged into nonaxisymmetric dark massive halo are discussed. Galaxy disks dynamics in the nonax…
Polygonal Structures in the Gaseous Disk: Numerical Simulations
S. A. Khoperskov, A. V. Khoperskov, M. A. Eremin +1
The results of numerical simulations of a gaseous disk in the potential of a stellar spiral density wave are presented. The conditions under which straightened spiral arm segments…
