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 study the possibility of producing axion dark matter (DM) via misalignment mechanisms
in a non-standard cosmological era dominated by ultra-light primordial black holes (PBH) …

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 …
