摘要：
Stellar-mass black holes come from the deaths of massive stars, and have been observed both in our own Galaxy and in other galaxies. Supermassive black holes have masses of up to 10,000,000,000 times the mass of the Sun and reside at the centers of galaxies. Intermediate-mass black holes (IMBHs), with masses in between these two regimes, are elusive and represent the missing link. When a compact object ventures too close the IMBH, it is captured because of the emission of gravitational waves, to be eventually swallowed whole when it crosses the event horizon. The process, an intermediate-mass ratio inspiral, represents a mapping of warped spacetime and can be observed with existing gravitational-wave ground-based detectors. Depending on the dynamical parameters, IMRIs can be detected jointly with space-borne ones, which will allow us to do multi-band width gravitational-wave astronomy.
