Resonant Effects of a Bar on the Galactic Disk Kinematics Perpendicular to Its Plane

Autor: Korchagin, Vladimir, Lutsenko, Artem, Tkachenko, Roman, Carraro, Giovanni, Vieira, Katherine

Publikováno v: Galaxies, 2023, 11(5), 97

Detailed analysis of kinematics of the Milky Way disk in the solar neighborhood based on the GAIA DR3 catalog reveals the existence of peculiarities in the stellar velocity distribution perpendicular to the galactic plane. We study the influence of r

The Influence of the Galactic Bar on the Dynamics of Globular Clusters

Autor: Tkachenko, Roman, Korchagin, Vladimir, Jmailova, Anna, Carraro, Giovanni, Jmailov, Boris

We make use of recent estimates for the parameters of the Milky Way's halo globular clusters and study the influence of the galactic bar on the dynamics of these clusters by computing their orbits. We use both an axisymmetric and non-axisymmetric gal

Gravitational Instability of Gas-Dust Circumnuclear Disks in Galaxies

Autor: Tkachenko, Roman, Korchagin, Vladimir, Jmailov, Boris

We numerically study the origin of the multi-armed spiral structure observed in the circumnuclear gaseous mini-disks of nearby galaxies. We show that the presence of dust in such disks and its interaction with the gravitationally stable gaseous compo
