Merging of spiral galaxies: observations and modeling
Alexander Khoperskov, Sergei Khrapov, Danila Sirotin +1
We present a study of the dynamics of multi-component models of spiral galaxies at various stages of grand merging. Numerical models include a self-consistent account of the dynami…
Formation of Transitional cE/UCD Galaxies through Massive/Dwarf Disc Galaxy Mergers
Alexander V. Khoperskov, Sergey S. Khrapov, Danila S. Sirotin
The dynamics of the merger of a dwarf disc galaxy with a massive spiral galaxy of the Milky Way type have been studied in detail. The remnant of such interaction after numerous cro…
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…
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…
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…
Numerical code for multi-component galaxies: from N-body to chemistry and magnetic fields
S. A. Khoperskov, E. O. Vasiliev, A. V. Khoperskov +1
We present a numerical code for multi-component simulation of the galactic evolution. Our code includes the following parts: -body is used to evolve dark matter, stellar dynamic…
