Description
We will introduce the "memory burden" effect in the context of black hole evaporation, and discuss how it may have profound impacts on the scenario in which primordial black holes constitute all or part of the dark matter. Within this context, we will discuss how the evaporation of primordial black holes in the local Universe may provide observables for constraining the mechanism and/or the scenario.
Most notably, neutrinos produced in the evaporation process are a so far little studied observable, and we use the latest IceCube data to place novel constraints on the combined parameter space of PBH masses and memory burden effects. Additionally, we have explored whether the ultra-high-energy neutrino event recently detected by KM3NeT could originate from an evaporating primordial black hole.
