DETECTING COALESCENCES OF INTERMEDIATE-MASS BLACK HOLES IN GLOBULAR CLUSTERS WITH THE EINSTEIN TELESCOPE

We discuss the capability of a third-generation ground-based detector such as the Einstein Telescope (ET) to detect mergers of intermediate-mass black holes (IMBHs) that may have formed through runaway stellar collisions in globular clusters. We find that detection rates of ~ 500 events per year are plausible.¹
