Abstract : Coalescences of stellar-mass black holes into intermediate-mass black holes (IMBHs) (M > 100 Solar Mass) are one of the exciting sources of gravitational waves (GWs). Observing GW signals from these sources provides unambiguous evidence for the existence of IMBHs. Although future space-borne and next-generation ground-based detectors are expected to observe many such signals if they exist, current ground-based interferometers may also detect them. Here, we consider current and future ground-based detectors to investigate the detectability of intermediate and high mass ratio massive binaries (200 Solar Mass < M < 1000 Solar Mass). We find that, if IMBH binaries do exist, the current and future generation detectors would be able to detect them, and including subdominant modes can appreciably improve the search sensitivity in some cases. We also explore the precision with which we will be able to measure the parameters of intermediate to high–mass–ratio binaries and probe the impact of subdominant modes in parameter estimations.
