The effect of stellar-mass black holes on the central kinematics of omega 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.

Mergers of accreting stellar-mass black holes [PDF]

, 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.

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.

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.

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.

Observable Signature of Merging Stellar-mass Black Holes in Active Galactic Nuclei [PDF]

Astrophysical Journal, 2023
The origin of stellar-mass black hole mergers discovered through gravitational waves is being widely debated. Mergers in the disks of active galactic nuclei (AGNs) represent a promising source of origin, with possible observational clues in the ...

Quasi-periodic oscillations of GHz-band polarization in a black hole [PDF]

Nature Communications
Relativistic 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 ...

The Mass Distribution of Stellar-Mass Black Holes [PDF]

, 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 five high-mass, wind-fed X-ray binary systems.

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.

The balance of power: accretion and feedback in stellar mass black holes [PDF]

, 2015
In this review we discuss the population of stellar-mass black holes in our galaxy and beyond, which are the extreme endpoints of massive star evolution. In particular we focus on how we can attempt to balance the available accretion energy with feedback
