Galaxies, 2023 We study radio and X-ray emissions from intermediate-mass black holes (IMBHs) and explore the unified model for accretion and ejection processes. The radio band survey of IMBH (candidate) hosted galaxies indicates that only a small fraction (∼0.6%) of ...

Intermediate-Mass Black Holes [PDF]
Annual Review of Astronomy and Astrophysics, 2020 We describe ongoing searches for intermediate-mass black holes with M BH ≈ 10–10 5 M ⊙ . We review a range of search mechanisms, both dynamical and those that rely on accretion signatures.

Intermediate-mass black holes and the Fundamental Plane of black hole accretion
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT We present new 5 GHz Very Large Array observations of a sample of eight active intermediate-mass black holes with masses 104.9 M⊙ < M < 106.1 M⊙ found in galaxies with stellar masses M* < 3 × 109 M⊙. We detected five of the eight sources at high significance.

INTERMEDIATE-MASS BLACK HOLES [PDF]
International Journal of Modern Physics D, 2004 The mathematical simplicity of black holes, combined with their links to some of the most energetic events in the universe, means that black holes are key objects for fundamental physics and astrophysics. Until recently, it was generally believed that black holes in nature appear in two broad mass ranges: stellar-mass (M~3–20 M⊙), which are produced ...

Mechanism for the suppression of intermediate-mass black holes [PDF]
Astronomy Letters, 2010 A model for the formation of supermassive primordial black holes in galactic nuclei with the simultaneous suppression of the formation of intermediate-mass black holes is presented. A bimodal mass function for black holes formed through phase transitions in a model with a "Mexican hat" potential has been found.

On the dynamic formation of accreting intermediate-mass black holes [PDF]
Astronomical and Astrophysical Transactions, 2007 We compute the probability that intermediate mass black holes (IMBHs) capture companions due to dynamical interactions and become accreting sources, and explore the possibility that the accreting IMBHs would appear as ultra-luminous X-ray sources (ULXs). We focus on IMBHs originating from low-metallicity Population III stars.

Rapid Intermediate-mass Black Hole Formation via Runaway Mergers of Black Holes
The Astrophysical Journal LettersObservations indicate that supermassive black holes in high-redshift galaxies formed on timescales far shorter than classical growth models allow. One hypothesis suggests intermediate-mass black hole (IMBH) seeds as an efficient growth channel.

Intermediate-mass black holes in globular clusters [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2012 Abstract There have been reports of possible detections of intermediate-mass black holes (IMBHs) in globular clusters (GCs). Empirically, there exists a tight correlation between the central supermassive black hole (SMBH) mass and the mean velocity dispersion of elliptical galaxies, ‘pseudo-bulges’ and classical bulges of spiral galaxies.
