Description:
Author(s): Rebecca J. Danos, Andrew R. Frey, and Yi Wang We utilize the Canny edge detection algorithm as an estimator for primordial non-Gaussianities. In preliminary tests on simulated sky patches with a window size of 57 degrees and multipole moments l up to 1024, we find a 99% distinction between maps with local non-Gaussianity | f NL |≈450 and Gaussian ...
