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 …

In the recent years, primordial black holes (PBHs) have emerged as one of the most
interesting and hotly debated topics in cosmology. Among other possibilities, PBHs could …

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 …

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 …

We present the fourth Open Gravitational-wave Catalog (4-OGC) of binary neutron star
(BNS), binary black hole (BBH), and neutron star–black hole (NSBH) mergers. The catalog …

We present the third open gravitational-wave catalog (3-OGC) of compact-binary
coalescences, based on the analysis of the public LIGO and Virgo data from 2015 through …

Detection of a gravitational-wave signal of non-astrophysical origin would be a landmark
discovery, potentially providing a significant clue to some of our most basic, big-picture …

We describe a search for gravitational waves from compact binaries with at least one
component with mass–and mass ratio q≥ 0.1 in Advanced Laser Interferometer …

Primordial black holes (PBHs), formed out of large overdensities in the early Universe, are a
viable dark matter (DM) candidate over a broad range of masses. Ultralight, asteroid-mass …

Gravitational waves from subsolar mass inspiraling compact objects would provide almost
smoking-gun evidence for primordial black holes (PBHs). We perform the first search for …
