On the correlation between globular clusters and the distribution of dark matter in galaxy clusters: the case of Abell 2744
Bright globular clusters in Abell 2744 trace the three main mass clumps and match weak-lensing mass maps more closely than other galactic components, using a Poisson point process model.
