Detecting cosmic strings in the CMB with the Canny algorithm

Detecting cosmic strings in the CMB with the Canny algorithm

Line discontinuities in cosmic microwave background anisotropy maps are a distinctive prediction of models with cosmic strings. These signatures are visible in anisotropy maps with good angular resolution and should be identifiable using edge-detection algorithms. One such algorithm is the Canny algorithm. We study the potential of this algorithm to …
