Tidal capture of stars by intermediate-mass black holes [PDF]
Monthly Notices of the Royal Astronomical Society, 2006 Recent X-ray observations and theoretical modelling have made it plausible that some ultraluminous X-ray sources (ULX) are powered by intermediate-mass black holes (IMBHs). N-body simulations have also shown that runaway merging of stars in dense star clusters is a way to form IMBHs.

Timing the starburst-AGN connection [PDF]
, 2010 The mass of super massive black holes at the centre of galaxies is tightly correlated with the mass of the galaxy bulges which host them. This observed correlation implies a mechanism of joint growth, but the precise physical processes responsible are a ...

The formation of intermediate mass black holes [PDF]
Symposium - International Astronomical Union, 2003 We study the growth rate of stars in dense star clusters by stellar collisions. Our analytic calculations are in good agreement with direct N-body simulations with up to 65536 stars performed on the GRAPE family of computers. We find that star clusters with a half mass relaxation time ≲ 20 Myr are dominated by stellar collisions.

A luminous X-ray outburst from an intermediate-mass black hole in an off-centre star cluster [PDF]
Nature Astronomy, 2018 A unique signature for the presence of massive black holes in very dense stellar regions is occasional giant-amplitude outbursts of multi-wavelength radiation from tidal disruption and subsequent accretion of stars that make a close approach to the black

mocca-survey Database I: Binary black hole mergers from globular clusters with intermediate mass black holes [PDF]
Monthly 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. Meanwhile, the probability to form intermediate mass black holes (IMBHs) also increases with the

POPULATION OF BLACK HOLES IN THE MILKY WAY AND IN THE MAGELLANIC CLOUDS
Acta Polytechnica, 2013 In this review, I will briefly discuss the different types of black hole (BH) populations (supermassive, intermediate mass and stellar mass BHs) both in the Galaxy and in the Magellanic Clouds and compare them with each other.

A Multimass Velocity Dispersion Model of 47 Tucanae Indicates No Evidence for an Intermediate-mass Black Hole [PDF]
Astrophysical Journal, 2018 In this paper, we analyze stellar proper motions in the core of the globular cluster 47 Tucanae to explore the possibility of an intermediate-mass black hole (IMBH) influence on the stellar dynamics.

The Hunt for Intermediate-mass Black Holes in the JWST Era [PDF]
The Astrophysical Journal, 2018 AbstractIntermediate-mass black holes (IMBHs), with masses between 100–105M⊙, fill the gap between stellar mass black holes and the supermassive black holes that reside in galaxy centers. While IMBHs are crucial to our understanding of black hole seed formation, black holes of less than ≈104M⊙have so far eluded detection by traditional searches ...
