Analysis of CMB maps with 2D Wavelets
We consider the 2D wavelet transform with two scales to study sky maps of temperature anisotropies in the cosmic microwave background radiation (CMB). We apply this technique to simulated maps of small sky patches of size 12.8◦ × 12.8◦ and 1.5′ × 1.5′ pixels. The relation to the standard approach, based on the C′ ls, is established through the introduction of the scalogram. We consider temperat...
متن کاملEllipticity analysis of the BOOMERanG CMB maps
The properties of the Cosmic Microwave Background (CMB) maps carry valuable cosmological information. Here we report the results of the analysis of ellipticity of the hot and cold CMB anisotropy spots in the BOOMERanG 150 GHz map. We carried out this analysis for the map obtained by summing independent measurement channels (signal plus noise map) and for a comparison map (noise only map) obtain...
متن کاملTopological Analysis of Cobe-dmr Cmb Maps
Geometric characteristics of random fields are exploited to test the consistency of density perturbation model spectra with COBE data. These CMB maps are analyzed using the number of anisotropy hot spots and their boundary curvature. CMB maps which account for instrumental effects and sky coverage are Monte Carlo generated. These simulations show that a scale invariant HarrisonZeldovich primord...
متن کاملCross-correlation studies with CMB polarization maps
The free-electron population during the reionized epoch rescatters the cosmic microwave background ~CMB! temperature quadrupole and generates a now well-known polarization signal at large angular scales. While this contribution has been detected in the temperature-polarization cross power spectrum measured with Wilkinson Microwave Anisotropy Probe data, due to the large cosmic variance associat...
متن کاملFast Clustering Analysis of Inhomogenous Megapixel CMB Maps
Szapudi et al. (2001) introduced the method of estimating angular power spectrum of the CMB sky via heuristically weighted correlation functions. Part of the new technique is that all (co)variances are evaluated by massive Monte Carlo simulations, therefore a fast way to measure correlation functions in a high resolution map is essential. This letter presents a new algorithm to calculate pixel ...
