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

open access: yesNature, 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 ...

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

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.

Radio Detections During Two State Transitions of the Intermediate-Mass Black Hole HLX-1 [PDF]

open access: yesScience, 2012
International audienceRelativistic jets are streams of plasma moving at appreciable fractions of the speed of light. They have been observed from stellar-mass black holes ($\sim$3$-$20 solar masses, M$_ \odot$) as well as supermassive black holes ($\sim ...

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.

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.

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.
