    • Planck 2018 results: I. Overview and the cosmological legacy of Planck 

      Aghanim, Nabila; Akrami, Yashar; Arroja, Frederico (EDP Sciences, 2020)
      The European Space Agency’s Planck satellite, which was dedicated to studying the early Universe and its subsequent evolution, was launched on 14 May 2009. It scanned the microwave and submillimetre sky continuously between ...

    • Planck 2018 results: V. CMB power spectra and likelihoods 

      Aghanim, Nabila; Akrami, Yashar; Ashdown, Mark A.J. (EDP Sciences, 2020)
      We describe the legacy Planck cosmic microwave background (CMB) likelihoods derived from the 2018 data release. The overall approach is similar in spirit to the one retained for the 2013 and 2015 data release, with a hybrid ...

    • Planck 2018 results: VI. Cosmological parameters 

      Aghanim, Nabila; Akrami, Yashar; Ashdown, Mark A.J. (EDP Sciences, 2020)
      We present cosmological parameter results from the final full-mission Planck measurements of the cosmic microwave background (CMB) anisotropies, combining information from the temperature and polarization maps and the ...

    • Planck 2018 results: VIII. Gravitational lensing 

      Aghanim, Nabila; Akrami, Yashar; Ashdown, Mark A.J. (EDP Sciences, 2020)
      We present measurements of the cosmic microwave background (CMB) lensing potential using the final Planck 2018 temperature and polarization data. Using polarization maps filtered to account for the noise anisotropy, we ...

    • Planck 2018 results: XII. Galactic astrophysics using polarized dust emission 

      Aghanim, Nabila; Akrami, Yashar; Alves, Marta I.R. (EDP Sciences, 2020)
      Observations of the submillimetre emission from Galactic dust, in both total intensity I and polarization, have received tremendous interest thanks to the Planck full-sky maps. In this paper we make use of such full-sky ...
