A part of the celestial sphere which has a cosmic string candidate (CSc-1 field) according to the radio data on cosmic microwave background anisotropy is statistically investigated to further substantiate this candidate. Cosmic strings are 1D cosmolo

The complexity of the cosmological scenario regarding cosmic strings (CSs) stands still in the way of a complete understanding. We describe here a promising strategy for the possible detection of these elusive physical entities. It is based on the se
