Non-Gaussianity in SMICA
M. Citran, H. V. Tran, G. Patanchon +1
We develop a new formalism for the component separation method Spectral Matching Independent Component Analysis (SMICA) in order to include the information contained in the foregro…
LiteBIRD science goals and forecasts: improved full-sky reconstruction of the gravitational lensing potential through the combination of Planck and LiteBIRD data
M. Ruiz-Granda, P. Diego-Palazuelos, C. Gimeno-Amo +102
Cosmic microwave background (CMB) photons are deflected by large-scale structure through gravitational lensing. This secondary effect introduces higher-order correlations in CMB an…
LiteBIRD Science Goals and Forecasts. -mode Anomalies
A. J. Banday, C. Gimeno-Amo, P. Diego-Palazuelos +101
Various so-called anomalies have been found in both the WMAP and Planck cosmic microwave background (CMB) temperature data that exert a mild tension against the highly successful b…
Constraints on primordial non-Gaussianity from Planck PR4 data
Gabriel Jung, Michele Citran, Bartjan van Tent +2
We perform the first bispectrum analysis of the final Planck release temperature and E-polarization CMB data, called PR4. We use the binned bispectrum estimator pipeline that was a…
