 Intermediate-mass black hole

An intermediate-mass black hole has a mass between stellar remnants and supermassive black holes, approximately $10^2$--$10^5{M}_{\odot }$.

Intermediate-mass black holes (IMBHs) are a class of black holes that have masses ranging between those of stellar black holes and supermassive black holes. While stellar black holes typically form from the collapse of massive stars and usually have masses between about 5 and 100 solar masses, supermassive black holes found at the centers of galaxies can have masses ranging from millions to billions of solar masses.
