Namely the solution of the problem of many bodies (N-body), especially for the central regions of galaxies, and the development the complete dynamic models of galactic nuclei. To do this, it is planned to solve the N-body problem by introducing to the modern high - performance codes for solution the gravitational problem of many bodies Nbody6++GPU and φ-GRAPE/GPU the new method of algorithmic regularization and calculate a set of models for galactic nuclei with broad characteristics. Since the problem of many bodies is widely used in celestial mechanics, astrophysics and cosmology, in particular, in modeling planetary systems, star clusters, galaxies and their clusters, as well as large-scale structure of the universe, the development of new approaches and codes to solve it is one of the most hot topic problems of nowadays computational astrophysics. popup.nrat_date 2024-12-09 Close
