Tests of Gaussianity
A. M. Aliaga, E. Martinez-Gonzalez, L. Cayon +4
We review two powerful methods to test the Gaussianity of the cosmic microwave background (CMB): one based on the distribution of spherical wavelet coefficients and the other on sm…
Contributions of point extragalactic sources to the Cosmic Microwave Background bispectrum
F. Argüeso, J. González-Nuevo, L. Toffolatti
All the analyses of Cosmic Microwave Background (CMB) temperature maps up--to--date show that CMB anisotropies follow a Gaussian distribution. On the other hand, astrophysical fore…
Goodness-of-Fit Tests to study the Gaussianity of the MAXIMA data
L. Cayon, F. Argueso, E. Martinez-Gonzalez +1
Goodness-of-Fit tests, including Smooth ones, are introduced and applied to detect non-Gaussianity in Cosmic Microwave Background simulations. We study the power of three different…
Wavelets Applied to CMB Maps: a Multiresolution Analysis for Denoising
J. L. Sanz, F. Argueso, L. Cayon +3
Analysis and denoising of Cosmic Microwave Background (CMB) maps are performed using wavelet multiresolution techniques. The method is tested on m…
Extragalactic Radio Sources and CMB anisotropies
L. Toffolatti, G. De Zotti, F. Argüeso +1
Confusion noise due to extragalactic sources is a fundamental astrophysical limitation for experiments aimed at accurately determining the power spectrum of the Cosmic Microwave Ba…
