@inproceedings{Pogosian2004ObservationalCO, title={Observational constraints on cosmic strings: Bayesian analysis in a three-dimensional parameter space}, author={Levon Pogosian and Mark Wyman and I. N. Wasserman}, year={2004} }

Current data exclude cosmic strings as the primary source of primordial density fluctuations. However, in a wide class of inflationary models, strings can form at later stages of inflation and have potentially detectable observational signatures. We study the constraints from WMAP and SDSS data on the fraction of primordial fluctuations sourced by local cosmic strings. The Bayesian analysis presented in this brief report is restricted to the minimal number of parameters. Yet it is useful for… CONTINUE READING
