Context. The WMAP satellite has made available high quality maps of the sky in five
frequency bands ranging from 22 to 94 GHz, with the main scientific objective of studying the …

We apply the multipole vector framework to full-sky maps derived from the first-year
Wilkinson Microwave Anisotropy Probe (WMAP) data. We significantly extend our earlier …

The non-Gaussian cold spot detected in wavelet space in the WMAP 1 yr data is detected
again in the co-added WMAP 3 yr data at the same position (b=-57, l= 209) and size in the …

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 non-Gaussian cold spot in the 1-yr Wilkinson Microwave Anisotropy Probe (WMAP)
data, described by Vielva et al. and Cruz et al., is analysed in detail in the present paper …

The main foundations of the standard Λ Λ CDM model of cosmology are that:(1) the redshifts
of the galaxies are due to the expansion of the Universe plus peculiar motions;(2) the cosmic …

The clustering of local extrema will be exploited to examine Gaussianity, asymmetry, and the
footprint of the cosmic-string network on the CMB observed by Planck. The number density …

We repeat the directional spherical real Morlet wavelet analysis, used to detect non-
Gaussianity in the Wilkinson Microwave Anisotropy Probe (WMAP) 1-yr data, on the WMAP …

We have produced a cleaned CMB temperature fluctuation map of the Wilkinson Microwave
Anisotropy Probe (WMAP) 3 year data using an improved internal linear combination (ILC) …

We have independently measured the genus topology of the temperature fluctuations in the
cosmic microwave background seen in the Wilkinson Microwave Anisotropy Probe (WMAP) …
