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 …

We update the constraints on the fraction of the Universe that may have gone into primordial
black holes (PBHs) over the mass range 10− 5 to 10 50 g. Those smaller than∼ 10 15 g …

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 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 …

Although the dark matter is usually assumed to be made up of some form of elementary
particle, primordial black holes (PBHs) could also provide some of it. However, various …

The possibility that the dark matter comprises primordial black holes (PBHs) is considered,
with particular emphasis on the currently allowed mass windows at 1 0 16–1 0 17 g, 1 0 20 …

We present our current best estimate of the plausible observing scenarios for the Advanced
LIGO, Advanced Virgo and KAGRA gravitational-wave detectors over the next several years …

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 …

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 …

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 …
