We consider wavelets as a tool to perform a variety of tasks in the context of analyzing cosmic microwave background (CMB) maps. Using Spherical Haar Wavelets we define a position and angular-scale-dependent measure of power that can be used to assess the existence of spatial structure. We apply planar Daubechies wavelets for the identification and removal of points sources from small sections of sky maps. Our technique can successfully identify virtually all point sources which are above 3…

Isotropic wavelets: a powerful tool to extract point sources from cosmic microwave background maps

It is the aim of this paper to introduce the use of isotropic wavelets to detect and determine the flux of point sources appearing in cosmic microwave background (CMB) maps. The most suitable wavelet

Testing the Gaussianity of the COBE DMR data with spherical wavelets

It is concluded that the spherical wavelet technique shows no strong evidence of non-Gaussianity in the COBE-DMR data, and the Gaussianity of the CMB data is investigated using an analysis based on spherical Haar wavelets.

The performance of spherical wavelets to detect non‐Gaussianity in the cosmic microwave background sky

We investigate the performance of spherical wavelets in discriminating between standard inflationary (Gaussian) and non-Gaussian models. For the latter we consider small perturbations of the Gaussian

Cumulants as non-Gaussian qualifiers

This work defines two new sets of statistics to quantify the level of non-Gaussianity in the cosmic microwave background and derives a series of properties concerning these statistics for a Gaussian random field and shows how one can relate these quantities to the higher order moments of temperature maps.
