MERGERS OF STELLAR-MASS BLACK HOLES IN NUCLEAR STAR CLUSTERS [PDF]

open access: bronze, 2008
Mergers between stellar-mass black holes (BHs) will be key sources of gravitational radiation for ground-based detectors. However, the rates of these events are highly uncertain, given that such systems are invisible.

POWERFUL, ROTATING DISK WINDS FROM STELLAR-MASS BLACK HOLES [PDF]

open access: greenAstrophysical Journal, 2015
We present an analysis of ionized X-ray disk winds found in the Fe K band of four stellar-mass black holes observed with Chandra, including 4U 1630−47, GRO J1655−40, H 1743−322, and GRS 1915+105.

Tidal Disruption on Stellar-mass Black Holes in Active Galactic Nuclei [PDF]

open access: yesAstrophysical Journal Letters, 2021
Active galactic nuclei (AGNs) can funnel stars and stellar remnants from the vicinity of the galactic center into the inner plane of the AGN disk. Stars reaching this inner region can be tidally disrupted by the stellar-mass black holes in the disk. Such

Mergers as a probe of particle dark matter

open access: yesSciPost Physics Proceedings, 2023
Black holes below Chandrasekhar mass limit (1.4 $M_{\odot}$) can not be produced via any standard stellar evolution. Recently, gravitational wave experiments have also discovered unusually low mass black holes whose origin is yet to be known.

Constraining High-redshift Stellar-mass Primordial Black Holes with Next-generation Ground-based Gravitational-wave Detectors [PDF]

open access: yesAstrophysical Journal Letters, 2022
The possible existence of primordial black holes in the stellar-mass window has received considerable attention because their mergers may contribute to current and future gravitational-wave detections. Primordial black hole mergers, together with mergers

Stellar-mass black holes in young massive and open stellar clusters – IV. Updated stellar-evolutionary and black hole spin models and comparisons with the LIGO-Virgo O1/O2 merger-event data [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2020
I present a set of long-term, direct, relativistic many-body computations of model dense stellar clusters with up-to-date stellar-evolutionary, supernova (SN), and remnant natal-kick models, including pair instability and pulsation pair instability ...

Constraints on the Cosmological Coupling of Black Holes from the Globular Cluster NGC 3201

open access: yesThe 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.

Ram-pressure Stripping of a Kicked Hill Sphere: Prompt Electromagnetic Emission from the Merger of Stellar Mass Black Holes in an AGN Accretion Disk [PDF]

open access: yesAstrophysical Journal, 2019
Accretion disks around supermassive black holes (SMBHs) are promising sites for stellar mass black hole (BH) mergers due to mass segregation and merger acceleration by disk gas torques. Here we show that a gravitational-wave (GW) kick at BH merger causes

Growth of Stellar-mass Black Holes in Dense Molecular Clouds and GW190521 [PDF]

open access: yes, 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,

Orbital Migration of Interacting Stellar Mass Black Holes in Disks around Supermassive Black Holes. II. Spins and Incoming Objects [PDF]

open access: yesAstrophysical Journal, 2018
The masses, rates, and spins of merging stellar mass binary black holes (BBHs) detected by aLIGO and Virgo provide challenges to traditional BBH formation and merger scenarios.
