Description
Axions can be produced thermally in the Early Universe leaving imprints in cosmological observables. I will discuss recent developments in the computation of the abundance of thermally produced axions and present improved cosmological constraints on axion interactions. Cosmology provides the strongest constraints to date on several axion couplings. Based on 2410.18186 and 2511.14864 and some preliminary results.
