 ====== Ideas for additional challenges ======
+===== Weighing dark remnants using luminous stars =====
+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).
+===== Dark remnants & IMBH =====
+Laura is applying her discrete Jeans modelling method to snapshots of N-body models that contain stellar-mass black holes. The idea is check if a concentration of dark remnants near the centre can be mistaken for an intermediate-mass black hole.
 ===== Pal 5 model from Andreas Kuepper in streams section =====

-===== Snapshots of an N-body model of M4 =====
+===== Mass modelling multiple-population GC with non-parametric method=====
+Apply Pascal Steger's non-parametric method (developed for dwarf galaxies) to mock data from N-body simulation of globular cluster with two distinct chemical populations.
+The data has the following format.
+^ $m$ ^ $x$ ^ $y$ ^ $z$ ^ $v_x$ ^ $v_y$ ^ $v_z$ ^ population ^
+|  [Msun] |  [pc]  |[pc]|[pc]| [km/s] | [km/s]   | [km/s]| [1 or 2] |
-As another source of mock data, snapshots from a large N-body simulation of the globular cluster M4 are [[http://datashare.is.ed.ac.uk/handle/10283/618?show=full| available here]]. Full lists of data for all particles (mass, position, velocity, stellar type, stellar radius, V magnitude, B-V colour) are given at almost 400 instants in the lifetime of the model. The simulation is described in the paper "Towards an N-body model of the globular cluster M4", submitted to MNRAS ([[http://arxiv.org/abs/1409.5597]]), which should be cited when making use of this data.
