Intermediate-mass black holes (IMBHs) span the approximate mass range 100-10100105105 Msun, between black holes (BHs) formed by stellar collapse and the supermassive BHs at the centers of galaxies. Mergers of massive BHs in a binary system are the most energetic gravitational-wave sources accessible by the ground-based gravitational-wave detector network, so is IMBH binary. The third observing run of the LIGO and Virgo detectors witnessed the first confirmed detection of an IMBH - GW190521, a system consistent with a binary merger with the total mass of ~1500 Msun. This merger with a component black hole in the pair-instability mass gap is likely to originate from an alternative formation channel. Here I will talk about recent findings from IMBH searches and source information about GW190521.
