The non-Gaussian cold spot detected in wavelet space in the WMAP 1-year data, is detected again in the coadded WMAP 3-year data at the same position (b = -57, l = 209) and size in the sky (around 10 degrees). The present analysis is based on several statistical methods: kurtosis, maximum absolute temperature, number of pixels below a given threshold, volume and Higher Criticism. All these methods detect deviations from Gaussianity in the 3--year data set at a slightly higher confidence level… Expand

Search for Non-Gaussianities in the WMAP Data with the Scaling Index Method
In the recent years, non-Gaussianity and statistical isotropy of the Cosmic Microwave Background (CMB) was investigated with various statistical measures, first and foremost by means of theExpand
Non-Gaussianity in the HILC foreground-reduced three-year WMAP CMB map
A detection or nondetection of primordial non-Gaussianity in the CMB data is essential not only to test alternative models of the physics of the early universe but also to discriminate among classesExpand
Scaling Indices Applied to the WMAP 5-Year Data
We continue the analysis of non-Gaussianities in the CMB by means of the scaling index method (SIM, Rath, Schuecker and Banday 2007) by applying this method on the single Q-, V-, W-bands and theExpand
Extragalactic Radio Sources and the WMAP Cold Spot
We detect a dip of 20%-45% in the surface brightness and number counts of NRAO VLA Sky Survey (NVSS) sources smoothed to a few degrees at the location of the WMAP cold spot. The dip has structure onExpand
Non-Gaussianity analysis on local morphological measures of WMAP data

CMB polarization as a probe of the anomalous nature of the Cold Spot
One of the most interesting explanations for the non-Gaussian Cold Spot detected in the WMAP data by Vielva et al. (2004), is that it arises from the interaction of the CMB radiation with a cosmicExpand
Constraints on primordial non-Gaussianity from a needlet analysis of the WMAP-5 data
We look for a non-Gaussian signal in the Wilkinson Microwave Anisotropy Probe (WMAP) 5-year temperature anisotropy maps by performing a needlet-based data analysis. We use the foreground-reduced mapsExpand
A scaling index analysis of the Wilkinson Microwave Anisotropy Probe three-year data: signatures of non-Gaussianities and asymmetries in the cosmic microwave background
Local scaling properties of the co-added foreground-cleaned three-year Wilkinson Microwave Anisotropy Probe (WMAP) data are estimated using weighted scaling indices a. The scaling index method is -Expand
Local properties of Wilkinson Microwave Anisotropy Probe cold spot
We investigate the local properties of WMAP Cold Spot (CS) by defining the local statistics: mean temperature, variance, skewness and kurtosis. We find that, compared with the \emph{coldest spots} inExpand
Needlet detection of features in the WMAP CMB sky and the impact on anisotropies and hemispherical asymmetries
We apply spherical needlets to the Wilkinson Microwave Anisotropy Probe 5-year cosmic microwave background (CMB) data set, to search for imprints of nonisotropic features in the CMB sky. We use theExpand
