[HTML][HTML] Ultraluminous X-ray sources

A King, JP Lasota, M Middleton - New Astronomy Reviews, 2023 - Elsevier
The study of ultraluminous X-ray sources (ULXs) has changed dramatically over the last
decade. In this review we first describe the most important observations of ULXs in various …

Primordial black holes—perspectives in gravitational wave astronomy

M Sasaki, T Suyama, T Tanaka… - Classical and Quantum …, 2018 - iopscience.iop.org
This article reviews current understanding of primordial black holes (PBHs), with particular

GWTC-3: Compact binary coalescences observed by LIGO and Virgo during the second part of the third observing run

R Abbott, TD Abbott, F Acernese, K Ackley, C Adams… - Physical Review X, 2023 - APS
The third Gravitational-Wave Transient Catalog (GWTC-3) describes signals detected with
Advanced LIGO and Advanced Virgo up to the end of their third observing run. Updating the …

GWTC-1: a gravitational-wave transient catalog of compact binary mergers observed by LIGO and Virgo during the first and second observing runs

BP Abbott, R Abbott, TD Abbott, S Abraham… - Physical Review X, 2019 - APS
We present the results from three gravitational-wave searches for coalescing compact
binaries with component masses above 1 M⊙ during the first and second observing runs of …

Binary black hole population properties inferred from the first and second observing runs of Advanced LIGO and Advanced Virgo

BP Abbott, R Abbott, TD Abbott… - The Astrophysical …, 2019 - iopscience.iop.org
The second LIGO/Virgo observing run (O2) spanned 9 months between 2016 November
and 2017 August, building on the first, 4-month run (O1) in 2015. The LIGO/Virgo …

GW170104: observation of a 50-solar-mass binary black hole coalescence at redshift 0.2

BP Abbott, R Abbott, TD Abbott, F Acernese, K Ackley… - Physical review …, 2017 - APS
We describe the observation of GW170104, a gravitational-wave signal produced by the
coalescence of a pair of stellar-mass black holes. The signal was measured on January 4 …

Formation and evolution of compact-object binaries in AGN disks

H Tagawa, Z Haiman, B Kocsis - The Astrophysical Journal, 2020 - iopscience.iop.org
The astrophysical origin of gravitational wave (GW) events discovered by LIGO/VIRGO
remains an outstanding puzzle. In active galactic nuclei (AGNs), compact-object binaries …

Candidate electromagnetic counterpart to the binary black hole merger gravitational-wave event s190521g

MJ Graham, KES Ford, B McKernan, NP Ross, D Stern… - Physical review …, 2020 - APS
We report the first plausible optical electromagnetic counterpart to a (candidate) binary black
hole merger. Detected by the Zwicky Transient Facility, the electromagnetic flare is …

The pair-instability mass gap for black holes

SE Woosley, A Heger - The Astrophysical Journal Letters, 2021 - iopscience.iop.org
Stellar evolution theory predicts a" gap" in the black hole birth function caused by the pair
instability. Many presupernova stars that have a core mass below some limiting value, M …
