Close encounters of black hole—star binaries with stellar-mass black holes
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT Dynamical interactions involving binaries play a crucial role in the evolution of star clusters and galaxies. We continue our investigation of the hydrodynamics of three-body encounters, focusing on binary black hole (BBH) formation, stellar disruption, and electromagnetic (EM) emission in dynamical interactions between a BH ...

Constraints on the Cosmological Coupling of Black Holes from the Globular Cluster NGC 3201
The Astrophysical Journal Letters, 2023 Globular clusters are among the oldest stellar populations in the Milky Way; consequently, they also host some of the oldest known stellar-mass black holes, providing insight into black hole formation and evolution in the early ( z ≳ 2) universe.

Growth of Stellar-mass Black Holes in Dense Molecular Clouds and GW190521 [PDF]
, 2020 A stellar-mass black hole can grow its mass noticeably through Bondi accretion, if it is embedded in an extremely dense and massive molecular cloud with slow motion with respect to the ambient medium for an extended period of time. This provides a novel,

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

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 central kinematics of ω Cen: a cautionary tale for IMBH interpretations [PDF]
Monthly notices of the Royal Astronomical Society, 2018 The search for intermediate-mass black holes (IMBHs) in the centre of globular clusters is often based on the observation of a central cusp in the surface brightness profile and a rise towards the centre in the velocity dispersion profiles.

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 ...
