Description
The accelerated motion of binary black holes (BBHs) can be constrained by the corresponding gravitational waves (GWs) they emit. We investigate the prospects of detecting this acceleration in future third-generation and proposed space-based GW detectors. Since this acceleration could be indicative of the binary's formation channel, we also forecast accelerations of BBHs in dense stellar environments detectable in the DECIGO and LISA eras. We focus in particular on globular clusters (GCs). We use the output of the Cluster Monte Carlo (CMC) large-scale N-body simulations of GCs to study the effect of cluster properties – metallicity 𝑍, virial and galactocentric radii 𝑟𝑣, 𝑟𝑔 – on the distribution of detectable accelerations. We find that Z and rv leave discernible imprints on the shape of the distributions of detectable accelerations and the corresponding BBH mass and redshift distributions. We thus demonstrate how future space-based detectors could provide novel probes of GCs.
