Reionization optical depth determination from Planck HFI data with ten percent accuracy
L. Pagano, J. -M. Delouis, S. Mottet +2
We present an estimation of the reionization optical depth from an improved analysis of the High Frequency Instrument (HFI) data of Planck satellite. By using an improved versi…
Planck 2018 results. V. CMB power spectra and likelihoods
Planck Collaboration, N. Aghanim, Y. Akrami +165
This paper describes the 2018 Planck CMB likelihoods, following a hybrid approach similar to the 2015 one, with different approximations at low and high multipoles, and implementin…
Planck 2018 results. VII. Isotropy and Statistics of the CMB
Planck Collaboration, Y. Akrami, M. Ashdown +147
Analysis of the Planck 2018 data set indicates that the statistical properties of the cosmic microwave background (CMB) temperature anisotropies are in excellent agreement with pre…
Planck 2018 results. IX. Constraints on primordial non-Gaussianity
Planck Collaboration, Y. Akrami, F. Arroja +157
We analyse the Planck full-mission cosmic microwave background (CMB) temperature and E-mode polarization maps to obtain constraints on primordial non-Gaussianity (NG). We compare e…
SRoll2: an improved mapmaking approach to reduce large-scale systematic effects in the Planck High Frequency Instrument legacy maps
J. -M. Delouis, L. Pagano, S. Mottet +2
This paper describes an improved mapmaking approach with respect to the one used for the Planck High Frequency Instrument 2018 Legacy release. The algorithm SRoll2 better corrects…
