Planck intermediate results. LV. Reliability and thermal properties of high-frequency sources in the Second Planck Catalogue of Compact Sources

Planck Collaboration, Y. Akrami, M. Ashdown +117

We describe an extension of the most recent version of the Planck Catalogue of Compact Sources (PCCS2), produced using a new multi-band Bayesian Extraction and Estimation Package (…

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. III. High Frequency Instrument data processing and frequency maps

Planck Collaboration, N. Aghanim, Y. Akrami +152

This paper presents the High Frequency Instrument (HFI) data processing procedures for the Planck 2018 release. Major improvements in mapmaking have been achieved since the previou…

Planck 2018 results. IV. Diffuse component separation

Planck Collaboration, Y. Akrami, M. Ashdown +150

We present full-sky maps of the cosmic microwave background (CMB) and polarized synchrotron and thermal dust emission, derived from the third set of Planck frequency maps. These pr…
