Abstract The Laser Interferometer Space Antenna (LISA) will be a transformative experiment
for gravitational wave astronomy, and, as such, it will offer unique opportunities to address …

Abstract The Laser Interferometer Space Antenna (LISA) has two scientific objectives of
cosmological focus: to probe the expansion rate of the universe, and to understand …

On May 21, 2019 at 03: 02: 29 UTC Advanced LIGO and Advanced Virgo observed a short
duration gravitational-wave signal, GW190521, with a three-detector network signal-to-noise …

The 100 years since the publication of Albert Einstein's theory of general relativity saw
significant development of the understanding of the theory, the identification of potential …

In this paper, which is of programmatic rather than quantitative nature, we aim to further
delineate and sharpen the future potential of the LISA mission in the area of fundamental …

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 …

We use the latest constraints on the population of stellar origin binary black holes (SOBBH)
from LIGO/Virgo/KAGRA (LVK) observations, to estimate the stochastic gravitational wave …

We conduct a thorough Bayesian analysis of the possibility that the black hole merger
events seen in gravitational waves are primordial black hole (PBH) mergers. Using the latest …

NANOGrav and other Pulsar Timing Arrays (PTAs) have discovered a common-spectrum
process in the nHz range that may be due to gravitational waves (GWs): if so, they are likely …

We investigate the stochastic gravitational-wave background (SGWB) produced by merging
binary black holes (BBHs) and binary neutron stars (BNSs) in the frequency ranges of Laser …
