Abstract

Imaging with the High Resolution Camera at the CFHT has been used to derive the radial distribution of globular clusters in M87 to within 10" (0.7 kpc) of its nucleus. The density profile of the globular cluster system shows a core radius of 1.0'+/- 0.1'(~4.6+/-0.5 kpc), ~30% smaller than inferred from earlier studies, but still an order of magnitude larger than the core radius of the inner galaxy light. This result is used to estimate an upper limit on the total mass which could have been removed from the M87 globular cluster system. This upper limit is only ~7.6 X 10^8^ M_sun_, which is less than 30% of the size of the compact nucleus (supermassive black hole) in M87.
