Hierarchical mergers of stellar-mass black holes and their gravitational-wave signatures

Nature Astronomy, 2021
While most of the compact-binary mergers detected by LIGO and Virgo are expected to consist of first-generation black holes formed from the collapse of stars, others might instead be of second (or higher) generation, containing the remnants of previous ...

Formation Channels of Single and Binary Stellar-Mass Black Holes

Handbook of Gravitational Wave Astronomy, 2021
These are exciting times for binary black hole (BBH) research. LIGO and Virgo detections are progressively drawing a spectacular fresco of BBH masses, spins and merger rates.

STELLAR-MASS BLACK HOLES

2014
This chapter examines stellar-mass black holes. The empirical study of black holes began in the 1960s with the discovery of quasars and the advent of X-ray astronomy. X-ray detectors could detect X-rays coming from a particular direction—as the instrument rotated, the detector scanned the sky.

Stellar Mass Black Hole for Engineering Optimization

2017
In recent years, nature-inspired algorithms have been popular due to the fact that many real-world optimization problems are increasingly large, complex and dynamic. By reasons of the size and complexity of the problems, it is necessary to develop an optimization method whose efficiency is measured by finding the near optimal solution within a ...

Stellar-Mass Black Hole Binaries as ULXs

AIP Conference Proceedings, 2005
Ultraluminous X‐ray sources (ULXs) with Lx > 1039 ergs s−1 have been discovered in great numbers in external galaxies with ROSAT, Chandra, and XMM‐Newton. The central question regarding this important class of sources is whether they represent an extension in the luminosity function of binary X‐ray sources containing neutron stars and stellar‐mass ...

Observational evidence for stellar mass black holes

Journal of Astrophysics and Astronomy, 1999
I review the evidence for stellar mass black holes in the Galaxy. The unique properties of the soft X-ray transient (SXTs) have provided the first opportunity for detailed studies of the mass-losing star in low-mass X-ray binaries. The large mass functions of these systems imply that the compact object has a mass greater than the maximum mass of a ...
