An Intermediate-mass black hole (IMBH) is a black hole whose mass is significantly more than stellar black holes (ten times to several tens of times the mass of the Sun) yet far less than supermassive black holes (one million to many million times the mass of the Sun). Considerably fewer of these objects are believed to exist when compared with the relative abundance of observed black holes in the stellar and supermassive mass ranges. Since the mechanisms by which IMBHs are formed are uncertain, it is consequently not entirely clear as why this significant discrepancy of relative abundances exists.

Famous quotes containing the words black and/or hole:
“Invention flags, his brain goes muddy,
And black despair succeeds brown study.”
—William Congreve (1670–1729)
“Steam was till the other day the devil which we dreaded. Every pot made by any human potter or brazier had a hole in its cover, to let off the enemy, lest he should lift pot and roof and carry the house away.”
