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 …

Dark matter represents currently an outstanding problem in both cosmology and particle
physics. In this review we discuss the possible explanations for dark matter and the …

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 …

Recent population studies have searched for a subpopulation of primordial black holes
(PBHs) in the gravitational-wave (GW) events so far detected by LIGO/Virgo/KAGRA (LVK) …

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 …

This article reviews current understanding of primordial black holes (PBHs), with particular
focus on those massive examples ($\gtrsim $$10^{15}~{\rm g} $) which remain at the …

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 …

Primordial black holes could have been formed in the early universe from nonlinear
cosmological perturbations reentering the cosmological horizon when the Universe was still …

The detection of gravitational waves from mergers of tens of Solar mass black hole binaries
has led to a surge in interest in primordial black holes (PBHs) as a dark matter candidate …

The recent detection by Advanced LIGO of gravitational waves (GW) from the merging of a
binary black hole system sets new limits on the merging rates of massive primordial black …
