Massive Black Holes in Star Clusters. I. Equal-mass clusters [PDF]

open access: yes, 2004
In this paper we report results of collisional N-body simulations of the dynamical evolution of equal-mass star clusters containing a massive central black hole.

Formation Scenarios for Intermediate-Mass Black Holes [PDF]

open access: yesAIP Conference Proceedings, 2003
Black holes with hundreds to thousands of solar masses are more massive than can be formed from a single star in the current universe, yet the best candidates for these objects are not located in gas-rich environments where gradual accretion could build up the mass. Three main formation scenarios have been suggested in the literature: that intermediate-

Supermassive black holes as the regulators of star formation in central galaxies

open access: yes, 2017
We present a relationship between the black hole mass, stellar mass, and star formation rate of a diverse group of 91 galaxies with dynamically-measured black hole masses.

Intermediate Mass Black Holes: Their Motion and Associated Energetics [PDF]

open access: yesAdvances in High Energy Physics, 2014
There is a lot of current astrophysical evidence and interest in intermediate mass black holes (IMBH), ranging from a few hundred to several thousand solar masses. The active galaxy M82 and the globular cluster G1 in M31, for example, are known to host such objects.

An escaping outflow in a galaxy with an intermediate-mass black hole

open access: yesMonthly Notices of the Royal Astronomical Society, 2023
ABSTRACT While in massive galaxies active galactic nucleus (AGN) feedback plays an important role, the role of AGN feedback is still under debate in dwarf galaxies. With well spatially resolved data obtained from the Multi-Unit Spectroscopic Explorer, we identify a spatially extended ($\rm \sim 3\,\, kpc$) and fast ($V_{80} \sim 471\,\, \

Black hole solutions in massive gravity [PDF]

open access: yes, 2009
The static vacuum spherically symmetric solutions in massive gravity are obtained both analytically and numerically. The solutions depend on two parameters (integration constants): the mass M (or, equivalently, the Schwarzschild radius), and an ...

Observational evidence for intermediate-mass black holes [PDF]

open access: yesInternational Journal of Modern Physics D, 2017
Intermediate-mass black holes (IMBHs), with masses in the range [Formula: see text]–[Formula: see text][Formula: see text]M[Formula: see text], are the link between stellar-mass BHs and supermassive BHs (SMBHs). They are thought to be the seeds from which SMBHs grow, which would explain the existence of quasars with BH masses of up to 10[Formula: see ...

Ratios of star cluster core and half-mass radii: a cautionary note on intermediate-mass black holes in star clusters

open access: yes, 2007
There is currently much interest in the possible presence of intermediate-mass black holes in the cores of globular clusters. Based on theoretical arguments and simulation results it has previously been suggested that a large core radius -- or ...

A Comparison of Intermediate Mass Black Hole Candidate ULXs and Stellar-Mass Black Holes [PDF]

open access: yes, 2004
Cool thermal emission components have recently been revealed in the X-ray spectra of a small number of ultra-luminous X-ray (ULX) sources with L_X > 1 E+40 erg/s in nearby galaxies.
