Density and kinematic cusps in M54 at the heart of the sagittarius dwarf galaxy: Evidence for A 104 M BLACK HOLE?
We report the detection of a stellar density cusp and a velocity dispersion increase in the center of the globular cluster M54, located at the center of the Sagittarius dwarf galaxy (Sgr). The central line-of-sight velocity dispersion is 20.2 ± 0.7 km s-
