Search for cosmic strings

We present a review of the current status of cosmic strings in theoretical and observational cosmology. Two independent methods to cosmic strings’ search in the Universe are considered: (a) a search for chains of gravitational lensing images of a special type in optical surveys with the help of tools of high angular resolution; (b) a study of the structure of CMB anisotropy in the data provided byWMAP and Planck missions. We also received new observational constraints on the energy of single cosmic string.
