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.
Mock datasets for all challenges from Gaia Challenge 2, 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.
Jeans modelling vs. Distribution-function based models for fitting mock data of GCs.
What will Gaia actually give us (for GCs, open clusters, runaway stars, hypervelocity stars)? What can we do with TGAS?
a) quantify biases from ignoring them
b) towards self-consistent mixture models with potential escapers
include prescription for rotation in multi-mass DF models.
