Formation of spiral dwarf galaxies: observational data and results of numerical simulation
Sergey Khrapov, Alexander Khoperskov, Natalia Zaitseva +2
Recent studies show the possibility of the formation of fairly regular and global spiral patterns in dwarf galaxies (dS type). Our sample of observed dwarf objects of this class al…
On the formation of spiral arms in dwarf galaxies
Anatoly V. Zasov, Alexander V. Khoperskov, Natalia A. Zaitseva +1
Spiral structure (both flocculent and Grand Design types) is very rarely observed in dwarf galaxies because the formation of spiral arms requires special conditions. In this work w…
Modeling of Spiral Structure in a Multi-Component Milky~Way-Like Galaxy
Sergey Khrapov, Alexander Khoperskov, Vladimir Korchagin
Using recent observational data, we construct a set of multi-component equilibrium models of the disk of a Milky Way-like galaxy. The disk dynamics are studied using collisionless-…
Extreme kinematic misalignment in IllustrisTNG galaxies: the origin, structure and internal dynamics of galaxies with a large-scale counterrotation
Sergey Khoperskov, Igor Zinchenko, Branislav Avramov +9
Modern galaxy formation theory suggests that the misalignment between stellar and gaseous components usually results from an external gas accretion and/or interaction with other ga…
Spiral structure of the Milky Way galaxy: observations and theoretical predictions
V. I. Korchagin, S. S. Khrapov, A. V. Khoperskov
Using observational data on the kinematical properties and density distributions of the subsystems of the Milky Way galaxy, we construct a set of multi-component equilibrium models…
Lagrange-Eulerian method for numerical integration of the gas dynamics equations: parallel implementation on GPUs
Sergey Khrapov, Alexander Khoperskov, Sergey Khoperskov
We describe a new CSPH-TVD method for numerical integration of hydrodynamical equations. The method is based on combined Lagrange-Euler approaches, and it has been devoted to simul…
Hic sunt dracones: Cartography of the Milky Way spiral arms and bar resonances with Gaia Data Release 2
S. Khoperskov, O. Gerhard, P. Di Matteo +5
In this paper we introduce a new method for analysing Milky Way phase-space which allows us to reveal the imprint left by the Milky Way bar and spiral arms on the stars with full p…
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…
