In the following years Very Long Baseline Interferometry (VLBI) facilities will be able to directly image the accretion flow around the supermassive black hole candidate at the center of the Milky Way, Sgr A*. They will also be able to observe its shadow: an optical property which appears as a consequence of the strong gravitational field around it and which thus depends only on the physical parameters of the black hole. While there is no definitive evidence of the nature of the spacetime geometry around Sgr A*, it has been usually modeled by a Kerr black hole, by virtue of the no-hair theorem, which asserts that all uncharged black holes in 4-dimensional general relativity are described by this metric and thus completely specified by two p...
