-==== Additional challenges ==== 
  
-A few more ideas, still in the early stages, were discussed during the workshop: 
- 
-A. [[:​tests:​collision:​gc2_archive:​challenge4|Challenge 4]]: Weighing dark remnants using luminous stars - Following discussions with Adriano, we decided to add another challenge in which we will explore how/if the mass function of dark remnants can be constrained from a limited set of observables,​ using mock data from N-body simulations. This could be part of Miklos’ project on Challenge 2. Provided that this works, we can then consider a direct application to real data (e.g. Gaia-ESO survey - some of us are members of the consortium). 
- 
-B. Mass modelling GCs with multiple populations - Pascal offered to apply his non-parametric method (developed for dwarf galaxies) to [[:​tests:​collision:​new_challenges|mock data from an N-body simulation of a globular cluster with two distinct chemical populations]]. We want to get a feeling for how well the method recovers the mass distribution of a GC, and also how much do we gain by considering two tracer populations with different phase-space distributions. 
- 
-C. Dark remnants & IMBH - Laura is applying her discrete Jeans modelling method to snapshots of N-body models that contain stellar-mass black holes (from [[:​tests:​collision:​challenge2|Challenge 2]]). The idea is check if a concentration of stellar-mass black holes near the centre can be mistaken for an intermediate-mass black hole. Anna S. has also been looking at the snapshots from Douglas Heggie’s M4 simulation, in particular at the potential kinematic signatures following the ejection of relatively massive black holes.
