POTENTIAL HUGENESS. “The existence of wandering IMBHs in high-mass galaxies will create a reservoir of IMBH-SMBH mergers waiting to happen. While some IMBHs will have dynamical friction timescales longer than a Hubble time, others will have orbits that decay and bring them into the centers of their hosts.” (IMBHs = intermediate mass black holes; SMBH = supermassive black holes).
