Modeling the motion of a bright spot in jets from black holes M87* and SgrA*

We study the general relativistic motion of a bright spot in jet from an accreting black hole. The corresponding lensed images moving are calculated numerically discrete time intervals along trajectory Kerr space-time framework. As representative examples, we consider cases supermassive holes SgrA* and M87*. Astrophysical observations spots jets provides unique possibility for verification different gravitation theories strong field limit.
