We also plan to study the impact of mergers on the chemical evolution of the halos and bulges of individual spiral and elliptical massive galaxies, as well as dwarf spheroidal galaxies of the Local Group. Additionally, we plan to investigate the content of rare earth elements in different ionization stages and analyze the magnetic field in various spectral lines of roAp stars in our Galaxy. We will also focus on the dynamic evolution of globular clusters using direct N-body modeling with variable gravitational potential models of our Galaxy, obtained from the Illustris TNG (100, 50) cosmological database. We will analyze the mass loss rates of the clusters, the distribution of black holes and neutron stars for each of the selected clusters. We will also examine possible close interactions between the clusters themselves (collisions or close passes and their interactions, including the exchange of cluster members) and the central supermassive black hole with the central star cluster in the Galaxy, including processes of tidal disruption (TD) of individual stars and the destruction of clusters. Another goal of the project is to study the dynamics of supermassive and intermediate-mass black holes in the centers of galaxies. The main physical models to be used in the simulations include: binary supermassive black holes with spins in dense environments, binary supermassive black holes in a torus, and systems of bound black holes in globular clusters. popup.nrat_date 2025-01-03 Close
