Formation of High Redshift Objects in a Cosmic String Theory with Hot Dark Matter

Abstract

Using a modification of the Zel'dovich approximation adapted to hot dark matter, the accretion of such matter onto moving cosmic string loops is studied. It is shown that a large number of $10^{12}{M}_{\odot }$ nonlinear objects will be produced by a redshift of $z=4$. These objects could be the hosts of high redshift quasars.
