A supra-massive population of stellar-mass black holes in the globular cluster Palomar 5. [PDF]
Nat Astron, 2021 Palomar 5 is one of the sparsest star clusters in the Galactic halo and is best known for its spectacular tidal tails, spanning over 20° across the sky.

Indirect Evidence for Dark Matter Density Spikes around Stellar-mass Black Holes [PDF]
The Astrophysical Journal Letters, 2023 It has been suggested for a long time that dark matter would form a density spike around a black hole. However, no promising evidence has been observed so far to verify this theoretical suggestion.

JWST CEERS and JADES Active Galaxies at z = 4–7 Violate the Local M •–M ⋆ Relation at >3σ: Implications for Low-mass Black Holes and Seeding Models [PDF]
The Astrophysical Journal Letters, 2023 JWST is revolutionizing our understanding of the high- z Universe by expanding the black hole horizon, looking farther and to smaller masses, and revealing the stellar light of their hosts.

Merging stellar-mass binary black holes [PDF]
Physics Reports, 2018 The LIGO and Virgo detectors have recently directly observed gravitational waves from several mergers of pairs of stellar-mass black holes, as well as from one merging pair of neutron stars.

SymmetryStellar-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 ...

THE MASS DISTRIBUTION OF STELLAR-MASS BLACK HOLES [PDF]
The Astrophysical Journal, 2010 We perform a Bayesian analysis of the mass distribution of stellar-mass black holes using the observed masses of 15 low-mass X-ray binary systems undergoing Roche lobe overflow and 5 high-mass, wind-fed X-ray binary systems.

Quasi-periodic oscillations of GHz-band polarization in a black hole [PDF]
Nature CommunicationsRelativistic jets from accreting black holes radiate non-thermal emission which is highly variable in different time scales. Previous studies on black holes of different mass scales, including supermassive and stellar-mass black holes, only report flux ...

Mergers of accreting stellar-mass black holes [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 We present post-Newtonian $N$-body simulations on mergers of accreting stellar-mass black holes (BHs), where such general relativistic effects as the pericenter shift and gravitational wave (GW) emission are taken into consideration.

Populations of Stellar-mass Black Holes from Binary Systems [PDF]
The Astrophysical Journal, 2019 In large and complicated stellar systems like galaxies, it is difficult to predict the number and characteristics of a black hole (BH) population. Such populations may be modeled as an aggregation of homogeneous (i.e., having uniform star formation ...

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