You will find here some challenges based on data from collisional N-body models. These mock data are designed to mimic collisional systems like star/globular clusters.

A summary of Gaia Challenge II from the Collisional systems working group can be found here. Preliminary results from the Gaia Challenge I workshop in Surrey are archived here.

Mock datasets for all challenges can be downloaded here.

Additional mock datasets and ideas for new challenges are listed here.

Links to some useful fitting and analysis tools are listed in the Tools section.

Ideas and challenges for the Gaia Challenge III workshop (Barcelona) are listed here.
