Revealing the general relativity effects in accretion events near a supermassive black hole
Original language description
We discuss the general relativity effects acting on the radiation signal from the inner accretion flow. We consider the radiation flux and polarization properties originating from a blob of gas near a rotating black hole. The predicted observed polarization at infinity is changed from its local value due to strong gravity and fast orbital motion. Different processes can produce the observed pattern: in the context of Sgr A* flares, the synchrotron mechanism and the inverse Compton up-scattering appear to be the most likely mechanisms.
