GW190412: Observation of a binary-black-hole coalescence with asymmetric masses

R Abbott, TD Abbott, S Abraham, F Acernese, K Ackley… - Physical Review D, 2020 - APS
We report the observation of gravitational waves from a binary-black-hole coalescence
during the first two weeks of LIGO's and Virgo's third observing run. The signal was recorded …

Detected stochastic gravitational waves and subsolar-mass primordial black holes

K Inomata, K Kohri, T Terada - Physical Review D, 2024 - APS
Multiple pulsar timing array (PTA) collaborations recently announced the evidence of
common-spectral processes caused by gravitational waves (GWs). These can be the …

Two populations of LIGO-Virgo black holes

G Hütsi, M Raidal, V Vaskonen… - Journal of Cosmology …, 2021 - iopscience.iop.org
We analyse the LIGO-Virgo data, including the recently released GWTC-2dataset, to test a
hypothesis that the data contains more than one population of black holes. We perform a …

[HTML][HTML] Solar-mass primordial black holes explain NANOGrav hint of gravitational waves

K Kohri, T Terada - Physics Letters B, 2021 - Elsevier
The NANOGrav collaboration for the pulsar timing array (PTA) observation recently
announced evidence of an isotropic stochastic process, which may be the first detection of …

Implications for the supermassive black hole binaries from the NANOGrav 15-year data set

YC Bi, YM Wu, ZC Chen, QG Huang - Science China Physics, Mechanics …, 2023 - Springer
Several pulsar timing array (PTA) collaborations, including NANOGrav, EPTA, PPTA, and
CPTA, have announced the evidence for a stochastic signal consistent with a stochastic …

Search for the isotropic stochastic background using data from Advanced LIGO's second observing run

BP Abbott, R Abbott, TD Abbott, S Abraham… - Physical Review D, 2019 - APS
The stochastic gravitational-wave background is a superposition of sources that are either
too weak or too numerous to detect individually. In this study, we present the results from a …

Tests of general relativity with GW150914

BP Abbott, R Abbott, TD Abbott, MR Abernathy… - Physical review …, 2016 - APS
The LIGO detection of GW150914 provides an unprecedented opportunity to study the two-
body motion of a compact-object binary in the large-velocity, highly nonlinear regime, and to …
