Problems of formation and evolution of bulges of spiral galaxies

Abstract

In this work, we develop the theory of the origin of galactic bulges, and gravitational instability of the bending, as well as modes of perturbation based on the background of a nonlinear non-stationary model. As a result, here, we propose critical diagrams and determine increments of instabilities for such types of perturbations. In addition, we also consider relationships between the masses of the bulge and the central black hole, which is of great importance in studying the evolution of the bulges of spiral galaxies. Moreover, problems on the evolution of bulges in spiral galaxies, together with discussions of their main species and physical mechanisms in their formation.
