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 …

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 compute the relic abundance of dark matter in the presence of Primordial Black Holes
(PBHs) beyond the semiclassical approximation. We take into account the quantum …

One of the fundamental characteristics of slow roll inflation is its generation of tensor
perturbations, which manifest as stochastic gravitational waves (GWs). Slow roll inflation …

We explore the possibility of explaining the observed dark matter (DM) relic abundance,
along with matter-antimatter asymmetry, entirely from the evaporation of primordial black …
