The first direct measurement of gravitational waves by the LIGO and Virgo collaborations
has opened up new avenues to explore our Universe. This white paper outlines the …

It is commonly assumed that the energy density of the Universe was dominated by radiation
between reheating after inflation and the onset of matter domination 54,000 years later …

We study the production of primordial black hole (PBH) binaries and the resulting merger
rate, accounting for an extended PBH mass function and the possibility of a clustered spatial …

Light primordial black holes may comprise a dominant fraction of the dark matter in our
Universe. This paper critically assesses whether planned and future gravitational wave …

It has been recently proposed that Hawking evaporation might slow down after a black hole
has lost about half of its mass. Such an effect, called" memory burden", is parameterized as …

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 …

We discuss the footprint of evaporation of primordial black holes (PBHs) on stochastic
gravitational waves (GWs) induced by scalar perturbations. We consider the case where …

High-frequency gravitational waves (HFGWs) are predicted in various exotic scenarios
involving both cosmological and astrophysical sources. These elusive signals have recently …

We present the new version v2. 0 of the public code BlackHawk designed to compute the
Hawking radiation of black holes, with both primary and hadronized spectra. This new …

Ultralight primordial black holes (PBHs)(≲ 10 9 g) completely evaporate via Hawking
radiation (HR) and produce all the particles in a given theory regardless of their other …
