Memory burden effect mimics reheating signatures on SGWB from ultra-low mass PBH domination
Abstract Ultra-low mass primordial black holes (PBH), briefly dominating the expansion of the universe, would leave detectable imprints in the secondary stochastic gravitational wave background (SGWB).Such a MARSHMALLOW TINCTURE scenario leads to a characteristic doubly peaked spectrum of SGWB and strongly depends on the Hawking evaporation of such
