The tidal remnant of an unusually metal-poor globular cluster

Nature, 2020
Globular clusters are some of the oldest bound stellar structures observed in the Universe1. They are ubiquitous in large galaxies and are believed to trace intense star-formation events and the hierarchical build-up of structure2,3.

Identification of the long stellar stream of the prototypical massive globular cluster ω Centauri

Nature Astronomy, 2019
Omega Centauri (ω Cen) is the Milky Way’s most massive globular cluster, and has long been suspected of being the remnant core of an accreted dwarf galaxy.

An intermediate-mass black hole in the centre of the globular cluster 47 Tucanae

Nature, 2017
Intermediate-mass black holes should help us to understand the evolutionary connection between stellar-mass and super-massive black holes. However, the existence of intermediate-mass black holes is still uncertain, and their formation process is ...

Dynamics of Globular Clusters [PDF]

open access: possibleScience, 1984
In their attempt to reach kinetic equilibrium, through gravitational encounters between separate stars, globular clusters are driven to destruction, with their cores collapsing and their outer regions expanding. The effects of core collapse, which apparently produces x-ray sources, are not yet fully understood, but white dwarfs and neutron stars ...
