The inner few parsecs at the Galactic Center have come under intense
scrutiny in recent years, in part due to the exciting broad-band
observations of this region, but also because of the growing interest from
theorists motivated to study the physics of black hole accretion, magnetized
gas dynamics and unusual star formation. The Galactic Center is now known
to contain arguably the most compelling supermassive black hole candidate,
weighing in at a little over 2.6 million suns. Its interaction with the nearby
environment, comprised of clusters of evolved and young stars, a molecular
dusty ring, ionized gas streamers, diffuse hot gas, and a hypernova
remnant, is providing a wealth of accretion phenomenology and high-energy
processes for detailed modeling. In this review, we summarize the latest
observational results, and focus on the physical interpretation of the most
intriguing object in this region - the compact radio source Sgr A*, thought
to be the radiative manifestation of the supermassive black hole.
