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 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 …

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 …

Abstract Weakly-and Feebly-Interacting Massive Particles (WIMPs and FIMPs) are among
the best-motivated dark matter (DM) candidates. In this paper, we investigate the production …

Primordial black holes (PBHs) are predicted in many models via different formation
mechanisms. Identifying the origin of PBHs is of the same importance as probing their …

A bstract Ultra-low mass primordial black holes (PBH), briefly dominating the expansion of
the universe, would leave detectable imprints in the secondary stochastic gravitational wave …

The postinflationary reheating phase is usually said to be solely governed by the decay of
coherently oscillating inflatons into radiation. In this submission, we explore a new avenue …

We compare the dark matter (DM) production processes and its parameters space in the
background of reheating obtained from two chief systems in the early Universe: the inflaton …

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 …

Supersymmetry predicts multiple flat directions, some of which carry a net baryon or lepton
number. Condensates in such directions form during inflation and later fragment into Q balls …
