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 hole, black and/or hole:
“The shadow of the Venetian blind on the painted wall,
Shadows of the snake-plant and cacti, the plaster animals,
Focus the tragic melancholy of the bright stare
Into nowhere, a hole like the black holes in space.”
—John Ashbery (b. 1927)
“I myself saw furious with blood
Neoptolemus, at his side the black Atridae,
Hecuba and the hundred daughters, Priam
Cut down, his filth drenching the holy fires.”
—Allen Tate (1899–1979)
“The absence on the panel of anyone who could become pregnant accidentally or discover her salary was five thousand dollars a year less than that of her male counterpart meant there was a hole in the consciousness of the committee that empathy, however welcome, could not entirely fill.”
