A Dynamical Survey of Stellar-mass Black Holes in 50 Milky Way Globular Clusters [PDF]
Astrophysical Journal, 2019 Recent numerical simulations of globular clusters (GCs) have shown that stellar-mass black holes (BHs) play a fundamental role in driving cluster evolution and shaping their present-day structure. Rapidly mass-segregating to the center of GCs, BHs act as

Radio Emission from an Ultraluminous X-Ray Source [PDF]
, 2003 The physical nature of ultraluminous x-ray sources is uncertain. Stellar mass black holes with beamed radiation and intermediate mass black holes with isotropic radiation are two plausible explanations.

Assisted inspirals of stellar mass black holes embedded in AGN discs: solving the ‘final au problem’ [PDF]
, 2016 We explore the evolution of stellar mass black hole binaries (BHBs) which are formed in the self-gravitating disks of active galactic nuclei (AGN). Hardening due to three-body scattering and gaseous drag are effective mechanisms that reduce the semi ...

The Analogous Structure of Accretion Flows in Supermassive and Stellar Mass Black Holes: New Insights from Faded Changing-look Quasars [PDF]
Astrophysical Journal, 2019 Despite their factor of ∼108 difference in black hole mass, several lines of evidence suggest possible similarities between black hole accretion flows in active galactic nuclei (AGN) and Galactic X-ray binaries.

The effect of stellar-mass black holes on the structural evolution of massive star clusters [PDF]
, 2007 We present the results of realistic N-body modelling of massive star clusters in the Magellanic Clouds, aimed at investigating a dynamical origin for the radius-age trend observed in these systems.

BlackCAT: A catalogue of stellar-mass black holes in X-ray transients [PDF]
, 2015 During the last ~50 years, the population of black hole candidates in X-ray binaries has increased considerably with 59 Galactic objects detected in transient low-mass X-ray binaries, plus a few in persistent systems (including ~5 extragalactic binaries).

The Astrophysical Journal, 2023 By using direct N -body numerical simulations, we model the dynamical coevolution of two supermassive black holes (SMBHs) and the surrounding stars in merging galaxies. In order to investigate how different stellar components evolve during the merger, we

Dynamics of Dwarf Galaxies Disfavor Stellar-Mass Black Holes as Dark Matter. [PDF]
Physical Review Letters, 2017 We study the effects of black hole dark matter on the dynamical evolution of stars in dwarf galaxies. We find that mass segregation leads to a depletion of stars in the center of dwarf galaxies and the appearance of a ring in the projected stellar ...

The Astrophysical Journal Letters, 2023 Observations have found black holes spanning 10 orders of magnitude in mass across most of cosmic history. The Kerr black hole solution is, however, provisional as its behavior at infinity is incompatible with an expanding universe.

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