Description
Extreme conditions in the magnetosphere of black holes cause a variety of interesting phenomena, that are subject to intensive studies in modern multi-messenger astrophysics. The central theme of this presentation is the analytical and numerical study of various high-energy radiative processes in the combined gravitational and electromagnetic fields, including the synchrotron radiation reaction and bremsstrahlung of charged particles moving in curved spacetime, scattering and decay of particles in the close vicinity of black holes, black hole energy extraction, and the treatment of chaos in the dynamical environment of black holes. The results of our theoretical studies can make fundamental contributions to understanding various currently investigated phenomena, such as relativistic jets, ultra-high-energy cosmic rays, black hole accretion disks, quasi-periodic oscillations, and others, where general relativistic effects with electromagnetic contributions are important.
