    • Cleaning foregrounds from single-dish 21 cm intensity maps with Kernel principal component analysis 

      Irfan, Melis O; Bull, Phillip (Oxford University Press, 2021)
      he high dynamic range between contaminating foreground emission and the fluctuating 21 cm brightness temperature field is one of the most problematic characteristics of 21 cm intensity mapping data. While these components ...

    • 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: VII. Isotropy and statistics of the CMB 

      Akrami, Yashar; Ashdown, Mark A.J.; Aumont, Jonathan (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 ...
