Abstract
We investigate large-angle anisotropies in the cosmic microwave radiation background which are induced by cosmic strings. We numerically evolve a string network from a redshift Z-100 to the present day and we use this data to generate a full-sky temperature map using sophisticated Green's function methods. Based on a limited number of realizations, we have compared the results of our simulations with the observations of the COBS-DMR experiment, demonstrating broad consistency. We have obtained a preliminary normalization for the string mass-per-unit-length mgr in the cosmic string scenario.
