Abstract: We start from a review of the construction of spherical wavelets and their use for Cosmological data analysis, focussing in particular on needlets. We discuss their statistical and analytic properties, and then we review a number of recent and less recent applications, such as the investigation for non-Gaussianity and asymmetries in Cosmic Microwave Background data and the search for point sources. We then consider extensions to three-dimensional settings, reviewing in particular the recent proposal of 3d radial needlets and their potential applications to future Large Scale Structure surveys.
