Gravitational Radiation from Intermediate-Mass Black Holes

, 2002
Recent X-ray observations of galaxies with ROSAT, ASCA, and Chandra have revealed numerous bright off-center point sources which, if isotropic emitters, are likely to be intermediate-mass black holes, with hundreds to thousands of solar masses.

On the Mass Distribution of Stellar-Mass Black Holes

Open Astronomy, 2014
The observational stellar-mass black hole mass distribution exhibits a maximum at about 8 M⊙. It can be explained via the details of the massive star evolution, supernova explosions, or consequent black hole evolution.

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 ...

Are stellar-mass binary black hole mergers isotropically distributed? [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT The Advanced LIGO and Advanced Virgo gravitational wave detectors have detected a population of binary black hole mergers in their first two observing runs. For each of these events, we have been able to associate a potential sky location region represented as a probability distribution on the sky.

Consequences of gravitational radiation recoil [PDF]

, 2004
Coalescing binary black holes experience an impulsive kick due to anisotropic emission of gravitational waves. We discuss the dynamical consequences of the recoil accompanying massive black hole mergers.

Electromagnetic Signals Following Stellar-mass Black Hole Mergers

The Astrophysical Journal Letters, 2017
Abstract It is often assumed that gravitational-wave (GW) events resulting from the merger of stellar-mass black holes are unlikely to produce electromagnetic (EM) counterparts. We point out that the progenitor binary has probably shed a mass ≳10 M ⊙ during its prior evolution.

The properties of primordially-seeded black holes and their hosts in the first billion years: implications for JWST

Astronomy & Astrophysics
Aims. James Webb Space Telescope (JWST) observations have opened a tantalising new window onto possible black holes as early as redshifts of z ∼ 10.4.
