This demonstrates the needs to add Post-Newtonian corrections even at the initial stage of galaxy mergers. The initial conditions for a system of triple black holes in a dense stellar environment in the galaxy NGC 6240 have been created. A unique merging tree was build for galaxies with a massive central objects.  Product Description popup.authors Ishchenko Maryna V. Bertsyk Peter P. popup.nrat_date 2021-12-16 Close
