Ionization from Cosmic Strings at Cosmic Dawn

Abstract

Cosmic strings produce charged particles which, by emitting electromagnetic radiation, partially ionize neutral hydrogen during the dark ages. Corrections to the ionization fraction of neutral hydrogen induced by cosmic strings could lead to new observational effects and/or new constraints on the string tension around $G\mu \sim 10^{-16}-10^{-22}$ for values of the primordial magnetic field in the range $B_0\sim 10^{-11}-10^{-9}$ Gauss.
