Early-Type Disk Galaxies: Structure and Kinematics

A. V. Zasov, A. V. Moiseev, A. V. Khoperskov +1

Spectroscopic observations of three lenticular (S0) galaxies (NGC 1167, NGC 4150, and NGC 6340) and one SBa galaxy (NGC 2273) have been taken with the 6-m telescope of the Special…

High resolution simulations of unstable modes in a collisionless disc

A. V. Khoperskov, A. Just, V. I. Korchagin +1

We present N-body simulations of unstable spiral modes in a dynamically cool collisionless disc. We show that spiral modes grow in a thin collisionless disk in accordance with the…

Formation of Ionization-Cone Structures in Active Galactic Nuclei: II. Nonlinear Hydrodynamic Modelling

V. L. Afanasiev, S. N. Dodonov, S. S. Khrapov +2

In Part I of this paper we described an equilibrium model of a jet in the gravitational field corresponding to the rigid-rotation region of the galactic disk. We used linear stabil…

Formation of Ionization-Cone Structures in Active Galactic Nuclei: I. Stationary Model and Linear Stability Analysis

V. L. Afanasiev, S. N. Dodonov, S. S. Khrapov +2

We discuss causes of the formation of the observed kinematics and morphology of cones of ionized matter in the neighborhood of the nuclei of Seyfert galaxies. The results of linear…

Bending instability in galaxies: the stellar disk thickness and the mass of spheroidal component

N. V. Tyurina, A. V. Khoperskov, D. V. Bizyaev

We present results of numerical N-body simulations of a galactic stellar disk embedded into a spherical dark halo. The non-linear dynamics of bending instabilities developing in th…

Helical structures in Seyfert galaxies

A. V. Moiseev, V. L. Afanasiev, S. N. Dodonov +2

The Seyfert galaxies with Z-shaped emission filaments in the Narrow Line Region (NLR) are considered. We assume that observable Z-shaped structures and velocity pattern of NLR may…
