Simulations predict intermediate-mass black hole formation in globular clusters

Science
The formation process of intermediate-mass black holes (IMBHs), defined as those between 100 and 105 solar masses (M⊙), is debated. One potential origin is the growth of less-massive black holes merging with stars and compact objects within globular ...

An intermediate-mass black hole in the centre of the globular cluster 47 Tucanae

Nature, 2017
Intermediate-mass black holes should help us to understand the evolutionary connection between stellar-mass and super-massive black holes. However, the existence of intermediate-mass black holes is still uncertain, and their formation process is ...

Dark Minihalos with Intermediate Mass Black Holes

Physical Review Letters, 2005
We argue that the Milky Way (MW) contains 10(3)-10(4) intermediate mass black holes (IMBHs) of mass approximately 10(2-3)M. Some IMBHs are naked, and some are enshrouded by dense dark minispikes and by minihalos of (10(6)-10(7))M circle. The IMBH is formed off-center by gas accretion in a minihalo.

The Hunt for Intermediate-Mass Black Holes

Science, 2005
Two types of black holes-stellar black holes and supermassive black holes-are known to exist in the universe. This leaves a large gap in the black hole mass distribution. In her Perspective, [Fabbiano][1] investigates whether ultraluminous x-ray sources may be the missing intermediate-mass black holes.

Intermediate-mass black holes in globular clusters [PDF]

Astrophysical Bulletin, 2011
The mass of central bodies in a number of Milky-Way globular clusters is estimated based on the stellar radial-velocity dispersion data. It is assumed that stars located close to the center of the cluster (i.e., to the black hole) rotate about it, have masses on the order of the solar mass, and that the mass of the gravitating center is greater by a ...

Intermediate-mass black hole found

Nature, 2017
The existence of medium-sized black holes has long been debated. Such an object has now been discovered in the centre of a dense cluster of stars, potentially enhancing our understanding of all black holes. See Letter p.203 Observational campaigns over several decades have targeted globular clusters

Miniquasars: Elusive Black Holes of Intermediate Mass [PDF]

, 2012
Confident that black holes of stellar (\( {5-15}\,\, \mathrm{M}_{\bigodot} \)) and super (\( 10^{5}-10^{10}\,\, \mathrm{M}_{\bigodot} \)) mass do indeed exist, astrophysicists began naturally to wonder if black holes outside of these mass ranges also existed.
