Globular clusters have long been used to test theories of stellar evolution, stellar dynamics, and galaxy formation. In recent years, these old clusters have emerged as fertile grounds to search for black holes and understand their formation. “Intermediate-mass” black holes have been proposed to lurk in their centres and could represent seeds from which super-massive black holes grow in the early universe. Dynamical formation of stellar-mass black hole binaries in the dense cores of globular clusters has also been suggested as a main formation channel for the sources of gravitational waves recently detected by the LIGO experiment. I will give an overview of the recent successes (and failures) of astronomers’ exciting hunt for black holes in globular clusters.

Bio: Vincent Hénault-Brunet recently joined NRC Herzberg as a Plaskett Fellow. He was born in Montreal, where he completed his BSc in physics from McGill and MSc in astrophysics from Université de Montréal. He then obtained his PhD from the Institute for Astronomy at the University of Edinburgh (UK), and was a research fellow at the University of Surrey (UK) and Radboud University (Netherlands) before moving to Victoria. His research focuses on stellar populations and globular clusters, in particular on the dynamics of stars in these systems.
