  • We present dynamical models for the massive globular cluster G1. The goal is to measure or place a significant upper limit on the mass of any central black hole. Whether or not globular clusters contain central massive black holes has important consequences for a variety of studies. We use new kinematic data obtained with Keck and new photometry from the Hubble Space Telescope (HST). The Keck spectra allow us to obtain kinematics out to large radii that are required to pin down the mass-to… CONTINUE READING
