Dark photon dark matter from a network of cosmic strings

We study the production of ultralight dark photons from a network of near-global, Abelian-Higgs cosmic strings. We find that dark photons produced in this way are nonrelativistic today and can make up all of the dark matter for dark photon masses as small as m A ~ 10 −22 eV.
