Statistical challenges in the analysis of cosmic microwave background radiation. (English) Zbl 1160.62097
Summary: An enormous amount of observations on Cosmic Microwave Background (CMB) radiation has been collected in the last decade, and much more data are expected in the near future from planned or operating satellite missions. These datasets are a goldmine of information for cosmology and theoretical physics; their efficient exploitation posits several intriguing challenges from the statistical point of view. We review a number of open problems in CMB data analysis and we present applications to observations from the Wilkinson Microwave Anisotropy Probe (WMAP) mission.
