Early structure formation from cosmic string loops Abstract
... Ref. [19] studied structure formation and reionization in this new string evolution scenario and found that the resulting bound on Gµ was competitive with the CMB and gravitational radiation bounds. In the present paper we shall reexamine early structure formation by cosmic strings and its effect on ...
