Tests of Gaussianity of CMB maps

We study two different methods to test Gaussianity in CMB maps. One of them is based on the partition function and the other on the morphology of hot and cold spots. The partition function contains information on all the mome nts and scales, being a useful quantity to compress the large data sets exp ected from future space missions like Planck. In particular, it contains mu ch richer information than the one available through the radiation power sp ectrum. The second method utilizes morphological properties of hot and cold spots such as the eccentricity and number of spots in CMB maps. We study t he performance of both methods in detecting non-Gaussian features in small scale CMB simulated maps as those which will be provided by the Planck miss ion.
