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.

Do Intermediate-Mass Black Holes Exist?

2014
This chapter addresses the existence of intermediate-mass black holes. There is powerful empirical evidence for two classes of black holes, namely, the stellar-mass black holes, with masses a few times that of the Sun, and the supermassive black holes at the centers of galaxies.

Intermediate-mass black holes in globular clusters

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 ...

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.

Miniquasars: Elusive Black Holes of Intermediate Mass

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.

Intermediate-mass black holes in globular clusters

2013
This work is focused on the search for intermediate-mass black holes (IMBHs) in the centers of globular clusters. It has been demonstrated that supermassive black holes (SMBHs) at the centers of galaxies show a tight correlation between their mass (M•) and the velocity dispersion (σ) of the galaxy.
