"Our Galactic Supermassive Black Hole Sgr A*: The Ideal Testbed for Theories of Accretion and Black Hole Life Cycles" Sgr A* is the weakest accreting black hole we have ever observed, yet it is not a particularly unique object. We know that the majority of galaxies harbor nuclei more like Sgr A* than bright active galactic nuclei (AGN), so our Galactic center represents a dominant stage in the "typical" life cycle of a spiral galaxy. I will discuss our current understanding of accretion around Sgr A*, the only source so far where we can directly image near-event horizon scales, and where semi-analytical models agree with sophisticated general relativistic magnetohydrodynamical simulations. These results provide a baseline for new progress on several major questions regarding the launching of relativistic jets, the acceleration of particles within these jets, and strong gravity effects, that are relevant for black holes of all mass scales.
