Title
Probing light primordial black holes through noncold dark matter
Speaker
Dr. Yu-Ming Chen (Carleton University, Canada )Abstract
In this talk, I will talk about the matter power spectrum constraint on primordial black holes (PBHs) by the dark matter (DM) emitted as Hawking radiation. I will particularly focus on light PBH that evaporates before big bang nucleosynthesis. On the DM side, only a fraction of the population is produced from PBH evaporation and interacts solely through gravity, while the remaining part is the regular CDM. By the precision measurement on the matter power spectrum from cosmic surveys, light PBH abundance can be tightly constrained.
