We combine proper motion data from Gaia EDR3 and HST with radial velocity data to study the stellar kinematics of the ωcen globular cluster. Using a steady-state, axisymmetric dynamical model, we measure the distribution of both the dark and luminous mass components. Assuming both exponential and NFW mass profiles, depending on the dataset, we measure an integrated mass of 104 − 106M within the ω-cen half-light radius for a dark component that is distinct from the luminous stellar component…
