The axion is a hypothetical, well-motivated dark-matter particle whose existence would explain the lack of charge-parity violation in the strong interaction. [...]

Dept. ; UC, Berkeley) ; De Amici, G (UC, Berkeley, Space Sci. Dept. ; UC, Berkeley) et al.
Measurements of the Cosmic Background Radiation (CBR) temperature have been performed at five wavelengths ranging from 0.33 to 12 cm. The results give a weighted average of 2.72 ~ 0.04 Kin agreement with the most recent data at higher frequencies and constrain possible Compton distorsions to less than 5%..

CMB-S4: Forecasting Constraints on Primordial Gravitational Waves / CMB-S4 Collaboration
CMB-S4---the next-generation ground-based cosmic microwave background (CMB) experiment---is set to significantly advance the sensitivity of CMB measurements and enhance our understanding of the origin and evolution of the Universe, from the highest energies at the dawn of time through the growth of structure to the present day.

Planck 2018 results. I. Overview and the cosmological legacy of Planck / Planck Collaboration
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 12 August 2009 and 23 October 2013, producing deep, high-resolution, all-sky maps in nine frequency bands from 30 to 857GHz. [...]

Exploring cosmic origins with CORE: Survey requirements and mission design / CORE Collaboration
Future observations of cosmic microwave background (CMB) polarisation have the potential to answer some of the most fundamental questions of modern physics and cosmology. In this paper, we list the requirements for a future CMB polarisation survey addressing these scientific objectives, and discuss the design drivers of the CORE space mission proposed to ESA in answer to the "M5" call for a medium-sized mission. [...]

Planck 2015 results. XI. CMB power spectra, likelihoods, and robustness of parameters / Planck Collaboration
This paper presents the Planck 2015 likelihoods, statistical descriptions of the 2-point correlation functions of CMB temperature and polarization. They use the hybrid approach employed previously: pixel-based at low multipoles, $\ell$, and a Gaussian approximation to the distribution of cross-power spectra at higher $\ell$. [...]

Planck 2015 results. XXVI. The Second Planck Catalogue of Compact Sources / Planck Collaboration
The Second Planck Catalogue of Compact Sources is a catalogue of sources detected in single-frequency maps from the full duration of the Planck mission and supersedes previous versions of the Planck compact source catalogues. It consists of compact sources, both Galactic and extragalactic, detected over the entire sky. [...]

Planck 2015 results. XXV. Diffuse low-frequency Galactic foregrounds / Planck Collaboration
(abridged) We discuss the Galactic foreground emission between 20 and 100GHz based on observations by Planck/WMAP. The Commander component-separation tool has been used to separate the various astrophysical processes in total intensity. [...]

Planck 2015 results. V. LFI calibration / Planck Collaboration
We present a description of the pipeline used to calibrate the Planck Low Frequency Instrument (LFI) timelines into thermodynamic temperatures for the Planck 2015 data release, covering 4 years of uninterrupted operations. As in the 2013 data release, our calibrator is provided by the spin-synchronous modulation of the CMB dipole, exploiting both the orbital and solar components. [...]

Planck 2015 results. XIII. Cosmological parameters / Planck Collaboration
We present results based on full-mission Planck observations of temperature and polarization anisotropies of the CMB. These data are consistent with the six-parameter inflationary LCDM cosmology. [...]
