Interacting galaxy NGC 6240. Research aim: 1. Data processing of the new release date of the spectral survey MaNGA DR15 (Mapping Nearby Galaxies at APO) 2. Research the peculiar velocity fields in the centers of galaxies. 3. Researching of the dynamic evolution of the supermassive black holes triple system in the center of the interacting galaxy NGC 6240 based on observations in the optical and radio bands. Research methods: Processing was performed using the ELF3D software package developed in 2015 to determine the parameters of emission lines and adapted by us for use in the UNG grid environment software package STARLIGHT. To study the dynamics of the system, a publicly available direct N-body code φ-GPU based on the C/C++ language was used. Results and their originality: As a result of the project, maps of the distribution of physical parameters were created for a large sample of galaxies: intensity of emission lines, velocity fields (and velocities dispersion) of gas and stars, oxygen and nitrogen abundances in the interstellar medium. We obtained the circular velocity curves of the gas and stellar disks of the galaxy UGC 4056. Using the image and color index g-r with SDSS, we determined the slope of the galaxy, which allows us to conclude that the galaxy rotates clockwise with spiral arms. Based on the physical data, three numerical models with the number of particles N = 67.5k, 135k, 270k and five different randomizations were constructed. According to the simulation results for all models, the bound system S1+S2 is formed in 4 million years. The formation of a hierarchical triple system occurs in 18 million years, but not for all sets of randomizations. The Lidov-Kozai effect was found between the orbits S (using the center of mass of the systems S1+S2) and N. Product Description popup.authors Sobolenko Margaryta O. popup.nrat_date 2020-12-26 Close
