We review numerous arguments for primordial black holes (PBHs) based on observational
evidence from a variety of lensing, dynamical, accretion and gravitational-wave effects. This …

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 …

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 …

We report on the population properties of compact binary mergers inferred from gravitational-
wave observations of these systems during the first three LIGO-Virgo observing runs. The …

The exploration of the universe has recently entered a new era thanks to the multi-
messenger paradigm, characterized by a continuous increase in the quantity and quality of …

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 …

The second Gravitational-Wave Transient Catalog, GWTC-2, reported on 39 compact binary
coalescences observed by the Advanced LIGO and Advanced Virgo detectors between 1 …

Neutron-star cores contain matter at the highest densities in our Universe. This highly
compressed matter may undergo a phase transition where nuclear matter melts into …

We report on gravitational-wave discoveries from compact binary coalescences detected by
Advanced LIGO and Advanced Virgo in the first half of the third observing run (O3a) between …

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 …
