Features of globular cluster’s dynamics with an intermediate-mass black hole
Open Astronomy, 2018 In this paper, we address the question of how a central intermediate-mass black hole (IMBH) in a globular cluster (GC) affects dynamics, core collapse, and formation of the binary population.

Spectrophotometric Reverberation Mapping of Intermediate-mass Black Hole NGC 4395
The Astrophysical JournalUnderstanding the origins of massive black hole seeds and their coevolution with their host galaxy requires studying intermediate-mass black holes (IMBHs) and estimating their mass.

Intermediate-mass black holes in galactic nuclei [PDF]
Proceedings of the International Astronomical Union, 2004 We present the first homogeneous sample of intermediate-mass black hole candidates in active galactic nuclei. Starting with broad-line active nuclei from the Sloan Digital Sky Survey, we use the linewidth-luminosity-mass scaling relation to select a sample of 19 galaxies in the mass range M_BH ~ 8 x 10^4 - 10^6 solar masses.

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.

Intermediate Mass Black Holes in Star Clusters [PDF]
Progress of Theoretical Physics Supplement, 2004 We have performed N-body simulations of the formation of intermediate mass black holes in young star clusters and the subsequent dynamical evolution of star clusters containing massive black holes. Our simulations show that runaway merging of massive main-sequence stars can produce an intermediate mass black hole in the M82 cluster MGG-11 if the ...

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.

Semiclassical S $$ \mathcal{S} $$ -matrix and black hole entropy in dilaton gravity
Journal of High Energy Physics, 2020 We use complex semiclassical method to compute scattering amplitudes of a point particle in dilaton gravity with a boundary. This model has nonzero minimal black hole mass M cr . We find that at energies below M cr the particle trivially scatters off the
