Multi-frequency spectral analysis of extragalactic radio sources in the 33-GHz VSA catalogue: sources with flattening and upturn spectrum
M. Tucci, J. A. Rubiño-Martin, R. Rebolo +11
We present an analysis of the spectral properties of the extragalactic radio sources in the nearly-complete VSA sample at 33GHz. Data from different surveys are used to study sourc…
The non-Gaussian Cold Spot in WMAP: significance, morphology and foreground contribution
M. Cruz, M. Tucci, E. Martinez-Gonzalez +1
The non--Gaussian cold spot in the 1-year WMAP data, described in Vielva et al. and Cruz et al., is analysed in detail in the present paper. First of all, we perform a more rigorou…
Limits on the detectability of the CMB B-mode polarization imposed by foregrounds
M. Tucci, E. Martinez-Gonzalez, P. Vielva +1
We investigate which practical constraints are imposed by foregrounds to the detection of the B-mode polarization generated by gravitational waves in the case of experiments of the…
Cross-correlation of the CMB and radio galaxies in real, harmonic and wavelet spaces: detection of the integrated Sachs-Wolfe effect and dark energy constraints
P. Vielva, E. Martinez-Gonzalez, M. Tucci
We report the first detection of the ISW effect in wavelet space, at scales in the sky around 7 degrees with a significance of around 3.3 sigma, by cross-correlating the WMAP first…
Predictions on high frequency polarization properties of extragalactic radio sources and implications for CMB polarization measurements
M. Tucci, E. Martinez-Gonzalez, L. Toffolatti +2
We present a method to simulate the polarization properties of extragalactic radio sources at microwave frequencies. Polarization measurements of nearly 2x10^6 sources at 1.4 GHz a…
An iterative destriping technique for diffuse background polarization data
C. Sbarra, E. Carretti, S. Cortiglioni +4
We describe a simple but effective iterative procedure specifically designed to destripe Q and U Stokes parameter data as those collected by the SPOrt experiment onboard the Intern…
