Stellar-Mass Black Holes [PDF]

open access: goldSymmetry
Stellar-mass black holes (3 M⊙≲MBH≲150 M⊙) are the natural product of the evolution of heavy stars (Mstar≳20 M⊙). In our Galaxy, we expect that 108–109 stellar-mass black holes have been formed from the gravitational collapse of heavy stars, but currently we know fewer than 100 objects.

Low-rate accretion onto isolated stellar-mass black holes [PDF]

open access: bronzeAstronomy & Astrophysics, 2005
Magnetic field behaviour in a spherically-symmetric accretion flow for parameters typical of single black holes in the Galaxy is discussed. It is shown that in the majority of Galaxy volume, accretion onto single stellar-mass black holes will be spherical and have a low accretion rate ($10^{-6} - 10^{-9}$ of the Eddington rate).

Observability of Isolated Stellar-mass Black Holes

open access: yesThe Astrophysical Journal Letters
Stellar-mass black holes (BHs) represent the natural end states of massive stars. It is estimated that 10 ^8 stellar-mass BHs are present in the Milky Way galaxy, a significant fraction of which are expected to be isolated.

Channels of Stellar-mass Black Hole Formation

open access: goldThe Astrophysical Journal
Abstract On the basis of a large collection of detailed 3D core-collapse supernova simulations carried to late times, we identify four channels of stellar-mass black hole formation. Our examples for Channel 1 can involve the formation of black holes in energetic asymmetric supernova explosions.

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.

Investigating stellar-mass black hole kicks [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2012
We investigate whether stellar-mass black holes have to receive natal kicks in order to explain the observed distribution of low-mass X-ray binaries containing black holes within our Galaxy. Such binaries are the product of binary evolution, where the massive primary has exploded forming a stellar-mass black hole, probably after a common envelope phase

Close encounters of black hole—star binaries with stellar-mass black holes

open access: yesMonthly 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

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.
