Primordial black holes are under intense scrutiny since the detection of gravitational waves
from mergers of Solar-mass black holes in 2015. More recently, the development of …

Gravitational waves (GWs) in the MHz–GHz frequency range are motivated by a host of early
Universe phenomena such as oscillons, preheating, and cosmic strings. We point out that …

Hawking evaporation of black holes in the early Universe is expected to copiously produce
all kinds of particles, regardless of their charges under the Standard Model gauge group. For …

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 Ultra-low mass primordial black holes (PBH), which may briefly dominate the
energy density of the universe but completely evaporate before the big bang …

Many cosmological phenomena lead to the production of primordial black holes in the early
Universe. These phenomena often create a population of black holes with extended mass …

A bstract Light primordial black holes (PBHs) with masses smaller than 10 9 g (10− 24 M⊙)
evaporate before the onset of Big-Bang nucleosynthesis, rendering their detection rather …

We propose a new way of probing the nonthermal origin of baryon asymmetry of the
Universe (BAU) and dark matter (DM) from evaporating primordial black holes (PBHs) via …

When rotating primordial black holes evaporate via Hawking radiation, their rotational
energy and mass are dissipated with different dynamics. We investigate the effect of these …

It is possible that primordial black holes constitute (or constituted) a significant fraction of the
energy budget of our universe. Terrestrial gravitational wave detectors offer the opportunity …
