The central mass and mass-to-light profile of the Galactic globular cluster M15
Mark den Brok, Glenn van de Ven, Remco van den Bosch +1
We analyze line-of-sight velocity and proper motion data of stars in the Galactic globular cluster M15 using a new method to fit dynamical models to discrete kinematic data. Our fi…
Local Group and Star Cluster Dynamics from HSTPROMO (The Hubble Space Telescope Proper Motion Collaboration)
Roeland P. van der Marel, Jay Anderson, Andrea Bellini +17
The Hubble Space Telescope (HST) has proven to be uniquely suited for the measurement of proper motions (PMs) of stars and galaxies in the nearby Universe. Here we summarize the ma…
Discrete dynamical modelling of omega Centauri
Laura L. Watkins, Glenn van de Ven, Mark den Brok +1
We present a new framework for modelling discrete kinematic data. Current techniques typically involve binning. Our approach works directly with the discrete data and uses maximum-…
