Mass modelling globular clusters: black holes and the IMF
Some of my recent work has focused on using and testing distribution function based multimass dynamical models and applying them to real data. These models capture the trend towards equipartition of different mass species and the resulting mass segregation in systems that are dynamically evolved due to two-body relaxation. They are very useful to infer the mass distribution within clusters, their global (initial) stellar mass function, their content of dark stellar remnants, including stellar-mass black holes, and also to address claims for the presence of intermediate-mass black holes in the centre of globular clusters (e.g. Gieles et al. 2018, Zocchi et al. 2017, Zocchi et al. 2019, Hénault-Brunet et al. 2019a, Hénault-Brunet et al. 2019b).
