Cosmological gravitational particle production (CGPP) is the creation of particles in an
expanding universe due solely to their gravitational interaction. These particles can play an …

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 …

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 …

We explore the possibility of producing the observed matter-antimatter asymmetry of the
Universe uniquely from the evaporation of primordial black holes (PBHs) that are formed in …

We investigate the role that the evaporation of light primordial black holes may have played
in the production of the baryon asymmetry of the Universe through high-scale leptogenesis …

We study the effect of an ultralight primordial black hole (PBH) dominated phase on the
gravitational wave (GW) spectrum generated by a cosmic string (CS) network formed as a …

In this article we investigate the cumulative stochastic gravitational wave spectra as a tool to
gain insight on the creation mechanism of primordial black holes. We consider gravitational …

We investigate the implications of memory burden on the gravitational wave (GW) spectrum
arising from the Hawking evaporation of light primordial black holes (PBHs). By considering …

We show, within the single-field inflationary paradigm, that a linear non-minimal interaction ξ
MP ϕ R between the inflaton field ϕ and the Ricci scalar R can result in successful inflation …
