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 …

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 …

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 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 …

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 …

We review conceptual aspects of inflationary scenarios able to produce primordial black
holes by amplifying the size of curvature fluctuations to the level required to trigger black …

We propose a novel primordial black hole (PBH) formation mechanism based on a first-
order phase transition (FOPT). If a fermion species gains a huge mass in the true vacuum …

In the post-LIGO era, there has been a lot of focus on primordial black holes (PBHs) heavier
than∼ 10 15 g as potential dark matter (DM) candidates. We point out that the branch of the …

A bstract Hawking evaporation of primordial black holes (PBHs) can facilitate the generation
of matter-antimatter asymmetry. We focus on ultra-low mass PBHs that briefly dominate the …
