Primordial non-Gaussianity: local curvature method and statistical significance of constraints on f_NL from WMAP data
P. Cabella, M. Liguori, F. K. Hansen +4
We test the consistency of estimates of the non-linear coupling constant f_{NL} using non-Gaussian CMB maps generated by the method described in (Liguori, Matarrese and Moscardini…
Theory of Cosmic Microwave Background Polarization
Paolo Cabella, Marc Kamionkowski
These lectures introduce some of the basic theory of cosmic microwave background (CMB) polarization with the primary aim of developing the theory of CMB polarization from inflation…
Asymmetries in the local curvature of the WMAP data
Frode K. Hansen, Paolo Cabella, Domenico Marinucci +1
We use the local curvature to investigate the possible existence of non-Gaussianity/asymmetry in the WMAP data. Considering the full sky we find results which are consistent with t…
Search for non-Gaussianity in pixel, harmonic and wavelet space: compared and combined
Paolo Cabella, Frode Hansen, Domenico Marinucci +2
We present a comparison between three approaches to test non-Gaussianity of cosmic microwave background data. The Minkowski functionals, the empirical process method and the skewne…
