Sagittarius dwarf galaxy flyaround

The distribution of stars in the shredded Sagittarius dwarf galaxy as revealed by the observations reported @ http://www.astro.virginia.edu/~mfs4n/sgr/
The image is based on the best model match to the map of 2MASS M-giant stars. The thin flat blue spiral represents the disk of our Milky Way galaxy (the shape and size of this disk is not derived as part of this work). The yellow dot represents the position of the Sun.
Sagittarius debris can be seen extending from the dense 'core' of the Sagittarius dwarf, wrapping around the galaxy, and descending through the Sun's position.
