Quiescent and active galactic nuclei as factories of merging compact objects in the era of gravitational wave astronomy
Galactic nuclei harbouring a central supermassive black hole (SMBH), possibly surrounded
by a dense nuclear cluster (NC), represent extreme environments that house a complex …

On the origin of GW190521-like events from repeated black hole mergers in star clusters
LIGO and Virgo have reported the detection of GW190521, from the merger of a binary black
hole (BBH) with a total mass around 150 M⊙. While current stellar models limit the mass of …

Repeated mergers, mass-gap black holes, and formation of intermediate-mass black holes in dense massive star clusters
Current theoretical models predict a mass gap with a dearth of stellar black holes (BHs)
between roughly 50 M⊙ and 100 M⊙, while above the range accessible through massive …

Resolving the peak of the black hole mass spectrum
Gravitational-wave (GW) detections of binary black hole (BH) mergers have begun to
sample the cosmic BH mass distribution. The evolution of single stellar cores predicts a gap …

Black hole mergers from hierarchical triples in dense star clusters
Hierarchical triples are expected to be produced by the frequent binary-mediated
interactions in the cores of globular clusters. In some of these triples, the tertiary companion …

A statistical solution to the chaotic, non-hierarchical three-body problem
NC Stone, NWC Leigh - Nature, 2019 - nature.com
The three-body problem is arguably the oldest open question in astrophysics and has
resisted a general analytic solution for centuries. Various implementations of perturbation …
