Abstract
New kinematic data based on the calcium IR triplet lines are presented that define rotation and velocity disersion profiles for the nuclei of M31 and M32 with high accuracy. New dynamical models are used to determine the mass distribution of the centers of these galaxies with much greater reliability than in the past. The results demonstrate that the nuclei rotate very rapidly and have very large mass-to-light ratios, recalling model A of Ostriker and Tremaine (1982) in the case of M31. The results strongly suggest the presence of massive black holes in the nuclei of both galaxies. 18 references.
