Recent analyses of the Wilkinson Microwave Anisotropy Probe (WMAP) data have suggested that the low-order multipoles of the cosmic microwave background (CMB) anisotropy distribution show cosmologically interesting and unexpected morphologies and amplitudes. In this paper, we apply a power equalization (PE) filter to the high-latitude WMAP data in order to reconstruct these low-l multipoles free from the largest Galactic foreground modelling uncertainties in the Galactic plane.

Multipole Vector Anomalies in the First-Year WMAP Data: A Cut-Sky Analysis

We apply the recently defined multipole vector framework to the frequency-specific first-year WMAP sky maps, estimating the low-l multipole coefficients from the high-latitude sky by means of a power

Cleaned 3 Year Wilkinson Microwave Anistropy Probe Cosmic Microwave Background Map: Magnitude of the Quadrupole and Alignment of Large-Scale Modes

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) method as a Galactic

On the cosmic microwave background large-scale angular correlations

Aims. We study the large-scale angular correlation signatures of the cosmic microwave background (CMB) temperature fluctuations from WMAP data in several spherical cap regions of the celestial

Effect of foregrounds on the cosmic microwave background radiation multipole alignment

We analyse the effect of foregrounds on the observed alignment of the cosmic microwave background radiation (CMBR) quadrupole and octopole. The alignment between these multipoles is studied by using

Signals of Statistical Anisotropy in WMAP Foreground-Cleaned Maps

Recently, a symmetry-based method to test for statistical isotropy of the cosmic microwave background was developed. We apply the method to template-cleaned 3- and 5-years Wilkinson Microwave

Bias in low-multipole cosmic microwave background reconstructions

The large-angle, low-multipole cosmic microwave background (CMB) provides a unique view of the largest angular scales in the Universe. Study of these scales is hampered by the facts that we have only

Can a primordial magnetic field originate large-scale anomalies in WMAP data?

Several accurate analyses of the cosmic microwave background (CMB) temperature maps from the Wilkinson Microwave Anisotropy Probe (WMAP) have revealed a set of anomalous results, at large angular

Large-angle correlations in the cosmic microwave background

It has been argued recently by Copi et al. 2009 that the lack of large angular correlations of the CMB temperature field provides strong evidence against the standard, statistically isotropic,

Can one reconstruct the masked cosmic microwave background sky

The cosmic microwave background (CMB) maps obtained by observations always possess domains, which have to be masked due to severe uncertainties with respect to the genuine CMB signal. Cosmological

Three-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Temperature Analysis

We present new full-sky temperature maps in five frequency bands from 23 to 94 GHz, based on data from the first 3 years of the WMAP sky survey. The new maps are consistent with the first-year maps
