Modern astrophysics is undergoing a period of rapid development, driven by the combination of observational data and high-performance computing. The program is aimed at creating an integrated scientific, methodological, and software platform for studying the evolution and dynamics of astrophysical objects-from close binaries and stars with circumstellar disks to active galactic nuclei and star clusters interacting with intermediate-mass black holes.
The main directions include: analysis of spectra and activity of Seyfert galaxies; development of statistical methods for selecting physical models; modeling the evolution of binary stars with the MESA module; investigation of the temporal evolution of circumstellar disks of Be/B[e] stars; observation and modeling of gamma-ray bursts and transients; study of equilibrium states of “star cluster-intermediate-mass black hole” systems; modeling of radial migration of stars in disk galaxies based on cosmological simulations; analysis of the role of fundamental scalar field in astrophysics and cosmology.
Implementation of the project will establish a unified physical and mathematical framework for interpreting observed phenomena, create a national infrastructure for data processing and modeling, and improve the accuracy and physical soundness of describing the processes that govern the formation and evolution of astrophysical objects on stellar and galactic scales.
The goal of the Program:
Conduct comprehensive theoretical, observational and numerical studies of astrophysical objects across scales — from stellar systems and active galactic nuclei to cosmological structures — to identify the fundamental physical laws governing the evolution of stars, galaxies, and the Universe as a whole
Tasks:
– Comprehensive study of the optical characteristics and activity specifics in the nuclei of selected Seyfert galaxies.
– Development of a methodology for the statistical selection of parametric models and its adaptation to the analysis of spectra of active galactic nuclei.
– Development and application of numerical methods for modeling the evolution of binary stellar systems using the MESA module.
– Investigation of the timescales of circumstellar disk evolution and their relation to the binarity of stars exhibiting Be and B[e] phenomena.
– Study of gamma-ray bursts and transients, including those associated with supernovae, kilonovae, fast radio bursts, and gravitational waves.
– Equilibrium states of stellar systems and intermediate-mass black holes in galactic centers.
– Investigation of radial migration of stars in disk galaxies formed in cosmological simulations.
– The role of a fundamental general-relativistic scalar field in astrophysics and cosmology.
