Abstract / Description:We report on a current investigation of the anisotropy pattern induced by cosmic
strings on the cosmic microwave background radiation (MBR). We have numerically evolved a
network of cosmic strings from a redshift of Z = 100 to the present and calculated the anisotropies
which they induce. Based on a limited number of realizations, we have compared the results of our
simulations with the observations of the COBE-DMR experiment. We have obtained a preliminary
estimate of the string mass-per-unit-length μ in the cosmic string scenario.
