In these lectures I explain the rudiments of Cosmic Microwave Background (CMB) data analysis. I then describe three novel methods which have been developed in the past few years: the iterative estimation of signal and noise from a CMB data stream, the construction of a non-Gaussian likelihood function and the estimate of higher order moments from CMB maps. These new methods rely on a detailed understanding...
After the recent measurement of the acoustic peak in the CMB anisotropy angular power spectrum at ~200, many analyses have found that the geometry of the Universe is nearly flat, while favoring slightly closed models. In this paper we will briefly remind how the CMB anisotropies depend on the curvature, explaining any assumptions we could make and showing that this 'skewness' towards closed models...
