Extensive simulations run by Prof. Rainer Spurzem (ZAH/ARI & <link http: www.kavlifoundation.org peking-university _self>Kavli Institute for Astronomy & Astrophysics at Peking University) support a new facet of globular clusters (GCs), i.e. they harbour a lot more black black holes than previously expected. Hitherto it was suggested that due to GC-internal dynamics black holes will be kicked out of these dense stellar systems. Instead, simulations following the paths of millions of stars over about 12 billion years have shown that significant numbers of black holes will be retained and the sort of BH-collisions<link https: www.ligo.caltech.edu news ligo20170601 external-link-new-window external link in new> recently detected for the third time by LIGO probably origin in such a cluster.
