Creating a high-precision proper motion catalogue for Omega Centauri
Omega Centauri is the most massive globular cluster of the Milky Way. Because of its high mass and its complex stellar populations, it is nowadays widely accepted to be the accreted nucleus of a dwarf galaxy. To decipher its formation history is an active field of research and can also help to understand the early merger history of the Milky Way. We want to contribute to this by reanalyzing Hubble Space Telescope data and creating a deep high-precision proper motion catalogue for the core of the cluster. Such a catalogue will enable interesting science studies such as the search for high proper motion stars (which could indicate the presence of an intermediate mass black hole) but also the study of the dynamics of different stellar populations.
