Description
I will present highlights of numerical simulations of gas falling onto a black hole in the center of the Milky Way. Our models predicts dynamical and radiative properties of a hot accretion flows around a Kerr black hole. I will show how the Sgr A* observational data put constraints on the model parameters such as viewing angle, spin of the black hole or mass accretion rate. Since there is a chance that the latter one might increase in the next few years, the image and spectrum of Sgr A* might also change. I will show one of the possible scenarios for the evolution of flux and size of the radio source. Finally, I will discuss the current models limitations and future prospects.
