    • Planck 2018 results IX. Constraints on primordial non-Gaussianity 

      Ballardini, M.; Akrami, Y.; Arroja, F. (EDP Sciences, 2020)
      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 estimates obtained from separable ...

    • Planck 2018 results VII. Isotropy and statistics of the CMB 

      BallardinI, M.; Akrami, Y.; Ashdown, M. (EDP Sciences, 2020)
      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 previous studies using the 2013 and 2015 data ...

    • Planck intermediate results. LVII. Joint Planck LFI and HFI data processing 

      Ballardini, M.; Akrami, Y.; Andersen, K. J. (ESO, 2020)
      We present the NPIPE processing pipeline, which produces calibrated frequency maps in temperature and polarization from data from the Planck Low Frequency Instrument (LFI) and High Frequency Instrument (HFI) using ...
