Title:   “Axion relics in non-standard cosmologies”

Abstract:  

I will review our recent findings in axion production by considering a non-standard expansion before Big Bang nucleosynthesis onset. I will start with cold dark matter production through the misalignment mechanism, assuming the energy density of the universe is dominated by a particle field described by a general equation of state. I will show the parameter space where the QCD axion is a dark matter candidate depending on the details of the non-standard cosmology. Finally, I will refer to our latest work, revisiting the features of axion thermal production during early matter domination or a late reheating era.
