One of the most interesting recent breakthroughs in modern physics is related with the experimental observation of gravitational waves, produced in the collision of black holes. Emerging gravitational-wave astronomy opens a new way of investigation of neutron stars and black holes, it provides unique insight into various cosmological phenomena. On the other hand, numerical simulation of collisions of black holes and neutron stars on supercomputers allows us to compare predictions of General Relativity with experimental data, so the capacity of numerical relativity to correctly reproduce various properties of cosmological objects is dramatically improved. \r\nBlack holes, boson stars and other cosmological objects are in focus of research of many physicists, among them the research teams of “Models of Gravity”, based in the Bremen-Oldenburg region. The proposed research project is a natural continuation of our previous collaboration with members of this group over last two decades. It serves the purpose of investigation of new types of black holes with synchronized matter fields. This study promises interesting new results, which may find various astrophysical applications, in particular, providing new opportunities for observational tests of the classical theory of gravity. On the other hand, it is related with the application of new advanced computational methods, which are developed to study complicated non-linear problems in various physical systems.
