Globular clusters. Galactic center. Supermassive black holes and their dynamical evolution. The aim of the work: One of the project's main objectives is to study the dynamical merger of supermassive black holes in galactic nuclei. Another task is to introduce the latest virtualization technologies to increase the overall efficiency of the observatory's IT infrastructure and to modernize the software for organizing access to and searching for data in the digital archives of the Ukrainian Virtual Observatory (UkrVO). Research methods: Numerical modeling using our well-known dynamic N-body φ-GPU code with post-Newtonian corrections, testing, analysis, and creation of information resources. We have investigated the dynamical evolution of the orbits of globular clusters (GCs) back in time by 10 billion years, using time-varying potentials that are closest to the physical parameters of the potential of our Galaxy. The results provided an answer to the question of the possibility of events and also made it possible to estimate the probability of close passes and the possibility of "collision" of the GCs with each other and with the central supermassive black hole in the past. The structure of the spectral database and software for its administration was created. During the implementation of this topic, technical support and maintenance of the websites of the MAO, UkrVO, KNIT, DBGPA, KPCB, AEROSOL-UA, Svitoglyad, the new version of the observatory website and the databases on which they are built were provided.   Product Description popup.authors Ivanov Daniil D.
