One of the most interesting recent breakthroughs in modern physics is related to the experimental observation of gravitational waves, produced in the collision of black holes. Emerging gravitational-wave astronomy opens a new way of investigating neutron stars and black holes and 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, dramatically improving the capacity of numerical relativity to correctly reproduce various properties of cosmological objects. Black holes, boson stars, and other cosmological objects are the focus of research for many physicists, among them the Models of Gravity research teams based in the Bremen-Oldenburg region. The proposed research project is a natural continuation of our previous collaboration with members of this group over the 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 and provide new opportunities for observational tests of the classical theory of gravity. On the other hand, the study is related to the application of new advanced computational methods, which are being developed to study complicated non-linear problems in various physical systems.
