Talk	Oral abstract	Title	Light from the Supermassive Black Hole in our Galaxy Center
Coauthors	Falcke, H.
Abstract	Recent advances in millimeter Very Long Baseline Interferometric technology and new telescopes have begun revealing the details of accretion disks and jet launching region of supermassive black holes. Over the last decade, models for accretion flows onto SMBHs have advanced from simple semi-analytical ones to highly sophisticated numerical simulations. The combination of four-dimensional (4-D) general relativistic magnetohydrodynamics simulations and 4-D general relativistic radiative transfer models allow us now to accurately predict the appearance of magnetized accretion flows and jets near a supermassive black hole. In my talk, I will present details of these numerical simulations and I will present how the current radio observations of the supermassive object in the center of our Galaxy already constrain many of the models parameters such as e.g. the black hole spin or the spin orientation with respect to the Galactic plane. I will also discuss the details of direct detection of the silhouette of the black hole event horizon in the center of our Galaxy.
