Populations of Stellar-mass Black Holes from Binary Systems [PDF]
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 ...

Galaxies, 2023 We study radio and X-ray emissions from intermediate-mass black holes (IMBHs) and explore the unified model for accretion and ejection processes. The radio band survey of IMBH (candidate) hosted galaxies indicates that only a small fraction (∼0.6%) of ...

Observing the shadows of stellar-mass black holes with binary companions [PDF]
Classical and quantum gravity, 2018 The observation of the shadows cast by the event horizon of black holes on the light emitted in its neighborhood is the target of current very-long-baseline-interferometric observations.

A Global Inventory of Feedback
Galaxies, 2023 Feedback from both supermassive black holes and massive stars plays a fundamental role in the evolution of galaxies and the inter-galactic medium. In this paper, we use available data to estimate the total amount of kinetic energy and momentum created ...

Circumbinary discs around merging stellar-mass black holes [PDF]
Monthly notices of the Royal Astronomical Society, 2018 A circumbinary disc around a pair of merging stellar-mass black holes may be shocked and heated during the recoil of the merged hole, causing a near-simultaneous electromagnetic counterpart to the gravitational wave event.

Science with the TianQin observatory: Preliminary results on stellar-mass binary black holes [PDF]
, 2020 We study the prospect of using TianQin to detect stellar-mass binary black holes (SBBHs). We estimate the expected detection number as well as the precision of parameter estimation on SBBH inspirals, using five different population models.

Stellar-mass black holes in young massive and open stellar clusters and their role in gravitational-wave generation II [PDF]
, 2017 The study of stellar-remnant black holes (BH) in dense stellar clusters is now in the spotlight, especially due to their intrinsic ability to form binary black holes (BBH) through dynamical encounters, that potentially coalesce via gravitational-wave (GW)

Orbital Migration of Interacting Stellar Mass Black Holes in Disks around Supermassive Black Holes
, 2019 The merger rate of stellar-mass black hole binaries (sBHBs) inferred by the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) suggests the need for an efficient source of sBHB formation.
