PROSPECTS FOR OBSERVING DYNAMICALLY FORMED BINARY BLACK HOLES IN THE LOCAL UNIVERSE WITH GRAVITATIONAL WAVES
Abstract
The dynamical evolution of globular clusters is expected to produce stellar-mass binary black holes with higher total mass than found in the field population of binary black holes. Such systems are identified as gravitational wave sources with the recent detections made by advanced Laser Interferometer Gravitational-Wave Observatory (aLIGO). We use the Monte Carlo code MOCCA to simulate the generation of binary black holes from globular clusters. These compact binary systems are found to be ejected quickly from the host globular clusters. Thereafter, they evolve independently due to the emission of gravitational radiation. We model the population of globular clusters for galaxies out to 30 Mpc and present the statistics of the results. At the end, we discuss here the prospects for detecting dynamically formed binary black holes at extragalactic distances using space-borne gravitational wave detectors.
