HET Brown Bag Seminar | Axions CDM in Non-Standard Cosmologies
Luca Visinelli (Stockholm University)
The properties of cold dark matter axions strongly depend on the thermal history of the Universe before BBN. I show that axion cold dark matter may be a good probe of the pre-BBN epoch since observational properties like the axion mass, its velocity dispersion, and the size of axion miniclusters can be used to distinguish among different scenarios.
