TY  - JOUR
AB  - Analysis of the Planck 2018 data set indicates that the statisticalproperties of the cosmic microwave background (CMB) temperature anisotropiesare in excellent agreement with previous studies using the 2013 and 2015 datareleases. In particular, they are consistent with the Gaussian predictions ofthe $\Lambda$CDM cosmological model, yet also confirm the presence of severalso-called "anomalies" on large angular scales. The novelty of the currentstudy, however, lies in being a first attempt at a comprehensive analysis ofthe statistics of the polarization signal over all angular scales, using eithermaps of the Stokes parameters, $Q$ and $U$, or the $E$-mode signal derived fromthese using a new methodology (which we describe in an appendix). Althoughremarkable progress has been made in reducing the systematic effects thatcontaminated the 2015 polarization maps on large angular scales, it is stillthe case that residual systematics (and our ability to simulate them) can limitsome tests of non-Gaussianity and isotropy. However, a detailed set of nulltests applied to the maps indicates that these issues do not dominate theanalysis on intermediate and large angular scales (i.e., $\ell \lesssim 400$).In this regime, no unambiguous detections of cosmological non-Gaussianity, orof anomalies corresponding to those seen in temperature, are claimed. Notably,the stacking of CMB polarization signals centred on the positions oftemperature hot and cold spots exhibits excellent agreement with the$\Lambda$CDM cosmological model, and also gives a clear indication of howPlanck provides state-of-the-art measurements of CMB temperature andpolarization on degree scales.
