A comparison of CMB Angular Power Spectrum Estimators at Large Scales: the TT case
Diego Molinari, Alessandro Gruppuso, Gianluca Polenta +5
In the context of cosmic microwave background (CMB) data analysis, we compare the efficiency at large scale of two angular power spectrum algorithms, implementing, respectively, th…
Cosmological Parameters from a re-analysis of the WMAP-7 low resolution maps
F. Finelli, A. De Rosa, A. Gruppuso +1
Cosmological parameters from WMAP 7 year data are re-analyzed by substituting a pixel-based likelihood estimator to the one delivered publicly by the WMAP team. Our pixel based est…
New constraints on Parity Symmetry from a re-analysis of the WMAP-7 low resolution power spectra
A. Gruppuso, F. Finelli, P. Natoli +4
The Parity symmetry of the Cosmic Microwave Background (CMB) pattern as seen by WMAP 7 is tested jointly in temperature and polarization at large angular scale. A Quadratic Maximum…
Power Asymmetries in the Cosmic Microwave Background Temperature and Polarization patterns
F. Paci, A. Gruppuso, F. Finelli +4
We test the asymmetry of the Cosmic Microwave Background anisotropy jointly in temperature and polarization. We study the hemispherical asymmetry, previously found only in the temp…
New estimates of the CMB angular power spectra from the WMAP 5 yrs low resolution data
A. Gruppuso, A. De Rosa, P. Cabella +5
A Quadratic Maximum Likelihood (QML) estimator is applied to the WMAP 5 year low resolution maps to compute the CMB angular power spectra at large scales for both temperature and p…
