Model-independent analyses of non-Gaussianity in Planck CMB maps using Minkowski functionals

Buchert, Thomas; France, Martin J.; Steiner, Frank

Despite the wealth of Planck results, there are difficulties in disentangling the primordial non-Gaussianity of the Cosmic Microwave Background (CMB) from the secondary and the foreground non-Gaussianity (NG). For each of these forms of NG the lack of complete data introduces model-dependences. Aiming at detecting the NGs of the CMB temperature an…
