- catalog abstract "Andrea Ghez lectures on the results of a motion study of the Galaxy's central stellar cluster with the W.M. Keck I 10-m telescope, which has shown measured star movements with velocities up to 1400 kn/s and, having accelerations of 3 mas/yr 2 at projected distances from the apparent radio counterpart of the black hole, Sgr A*. These measurements provide us with direct dynamical evidence for a 2.6 x 10 6 Mo central black hole, and also have permitted us to begin to constrian the orbits of these stars.".
