Detecting coalescences of intermediate-mass black holes in globular clusters with the Einstein Telescope

TL;DR

This paper evaluates the Einstein Telescope's potential to detect intermediate-mass black hole mergers in globular clusters, estimating a plausible detection rate of 500 events annually.

Contribution

It assesses the detection capabilities of a third-generation gravitational wave detector for intermediate-mass black hole mergers in globular clusters, providing estimated detection rates.

Findings

Detection rate of 500 events per year is plausible

The Einstein Telescope can effectively detect intermediate-mass black hole mergers

Runaway stellar collisions may produce detectable black hole mergers

Abstract

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