Evaporation of primordial black holes with multimodal mass and extended spin distributions: cosmological imprints on the effective number of relativistic species

Abstract Primordial black holes (PBHs) form through several distinct mechanisms, each imprinting a characteristic mass function that a single-mass treatment risks erasing. Building on the code, we introduce ( https://doi.org/10.5281/zenodo.22699162 ), implementing four mass funct...
