The spectrum of axions in a scaling string network
José Correia, Mark Hindmarsh, Joanes Lizarraga +3
Cosmic strings formed when the Peccei-Quinn symmetry breaks post-inflation are expected to emit axions throughout their lifetime. The details of the evolution of this network and t…

Scaling density of axion strings in terasite simulations
José Correia, Mark Hindmarsh, Joanes Lizarraga +3
We report on a study of axion string networks using fixed-grid simulations of up to points per side. The length of string can be characterised in terms of standard dimensio…
