Edge Detection, Cosmic Strings and the South Pole Telescope

We develop a method of constraining the cosmic string tension $Gμ$ which uses the Canny edge detection algorithm as a means of searching CMB temperature maps for the signature of the Kaiser-Stebbins effect. We test the potential of this method using high resolution, simulated CMB temperature maps. B...
