Fine-tuning in mixed Dark Matter models with Primordial Black Hole relics
Amirah Aljazaeri, Christian T. Byrnes
We investigate the fine-tuning of a tripartite dark matter (DM) scenario involving ultra-light primordial black holes (PBHs), whose evaporation before Big Bang Nucleosynthesis leav…

Comprehensively Constraining Ultra-Light Primordial Black Holes Through Relic Formation and Early Mergers
Amirah Aljazaeri, Christian T. Byrnes
We investigate constraints on the least explored, smallest mass scales of primordial black holes (PBHs), which evaporate prior to Big Bang Nucleosynthesis (BBN). Our study examines…
