Abstract
The Sagittarius dwarf galaxy, located at a distance of ∼ 15 kpc behind the Galactic bulge, is in the process of being tidally disrupted and assimilated into the Milky Way. This unique event allows the physics of galactic merging to be probed in unprecedented detail, and may shed light on the hypothesized population of primordial galaxies that merged to form the Milky Way.
