Searching for non-Gaussianity in the observational cosmic microwave background data


Special Astrophysical Observatory, Russian Academy of Sciences, Nizhnii Arkhyz, Zelenchukskiy Region, Karachai-Cherkessian Republic, Russian Federation

Methods for searching for non-Gaussianity in the WMAP data are reviewed and the associated problems related to the cosmic microwave background (CMB) data analysis are discussed. Evidence for non-Gaussianity has been obtained by various methods and from a number of multipole ranges. Different approaches to searching for non-Gaussian CMB data are sensitive to different manifestations of non-Gaussianity, which sometimes are due to the primordial non-Gaussianity and sometimes to galactic foregrounds and/or systematic residuals remaining after the data analysis that are difficult to take into account.
