The subject of research will be the electromagnetic processes that are currently considered as a tentative explanation of the origin of flares in the Galactic center. Related to that are mechanisms of efficient acceleration of cosmic ray particles to very high energy in active galaxies. These processes are associated with strong gravity near compact objects and the relativistic frame dragging. This is expected to be mainly theoretical work accompanied by numerical simulations and modeling.
