Dark Minihalos with Intermediate Mass Black Holes [PDF]

open access: yesPhysical 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? [PDF]

open access: yes, 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

mocca-survey Database I: Binary black hole mergers from globular clusters with intermediate mass black holes [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2020
The dynamical formation of black hole binaries in globular clusters that merge due to gravitational waves occurs more frequently in higher stellar density.

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 Galactic Globular Clusters

AIP Conference Proceedings, 2010
In this study, we present kinematics of the very centers of Omega Centauri and 47 Tucanae, obtained on the VLT using Fabry‐Perot observations behind an adaptive optics system. The Fabry‐Perot technique provides a unique tool to probe the central regions of crowded fields.

Intermediate-mass black holes in star clusters and dwarf galaxies [PDF]

open access: yes
Black holes (BHs) with masses between 100 to 100,000 times the mass of the Sun ($\rm{M}_{\odot}$) are classified as intermediate-mass black holes (IMBHs), potentially representing a crucial link between stellar-mass and supermassive BHs. Stellar-mass BHs
