Description
The cosmological history of axions is most predictive when their associated symmetry is restored in the post-inflationary universe, producing a network of cosmic strings. On the other hand, arguably the most well-motivated (high-quality) axions — those arising from extra dimensions and string theory — are often thought to be in tension with this scenario. In this talk, I explain how these are easily reconciled from a theoretical point of view and discuss phenomenological prospects.
