====== GC2: Challenge 4 ======

===== Weighing dark remnants using luminous stars =====

**Participants**: Adriano Agnello, Mark Gieles, Vincent Henault-Brunet, Miklos Peuten, Alice Zocchi

Questions to address:

   - Provided that multi-mass models do a good job in describing the kinematics (see Challenge 2), can we derive the mass function of the remnants from the luminous stars and the kinematics?
   - How does this depend on the retention fraction of black holes?


The snapshots from [[:tests:collision:mock_data|section B of the Mock data page]] can be used to tackle this challenge.
